Let’s be honest, how many people are watching this right before their test?

you already know test day is tmr. Edit: Guys and gals, I was a sophomore when I wrote this comment. I’m now in college and I still cannot do math for shit. I work a part time retail job and I have to have my phone calculator out to do anything with math. Thanks for blowing my comment up 😂

Shortcut! SSS - all sides SAS - the A is in the middle, so the angle is included between the sides ASA - the S is in the middle, so the side is included between the angles AAS - the S is on the side, so it is not included between the angles (because it is excluded on the side) Hope this helps!

I just love how everybody who comment on this wasn’t prepared for their test at all

3 days of my my teacher explaining this=nothing 3 minutes into this vid and I understand it.

Damn I wish he was my teacher, ive learned more in 1 hr than ive learned in 3 months

I learned all this in an hour and couldnt learn it in 2 weeks with my Math Teacher, I wish you were my teacher

It's 1 am and I have a geometry test tomorrow..? Today? Whatever.

I have a geometry test tomorrow and my teacher has been teaching this for 4 days. I didn't understand it at all, and I was so confused. I am now 10 minutes into this video and I understand it all. Thank you so much.

I love how my teacher doesn’t even bother teaching this subject himself and tells my class to go on KZfaq. This is honestly better and I think my teacher knows it.

My geometry test is in 8 hours. I’m not ready. Hopefully this works. 👏

This really helps cuz online classes are even worse than face to face. Anyone else here in 2020?

It's a different struggle to cry over a math problem

Best 50 minutes of my life. I'm back from school and the test was very easy thanks so much

Didn’t understand this the entire month my teacher spent on it, five minutes into the video and I’m going through my review packet fast as hell. You’re a life saver 😭

To anyone intimidated by the length of the video, I watched the video all the way through, and it was ENTIRELY worth it. Genuinely starting to understand the topic!

I have finals next week and I am going through this guy's videos so I can get a better understanding, anybody else dealing with the stress of finals coming up?

I've been learning this particular subject for like 2-3 weeks now and haven't understood NOTHING, til this video. Thank you so freaking much. I have to take a unit test tomorrow and i feel ready because of this video.

atleast this teacher wont shout at me when I couldnt understand the lesson

Wow thank you so much I was so lost before and this helped more than my geometry teacher ever did

Aced my test bro. Thank you so much

4 years later but still extremely helpful for students, thank you so much

gotta geometry final tomorrow and i’m the only one who has to take it and idek what i’m doing😚✌🏻

MR. Organic Chemistry Tutor, thank you for another long-extended video/lecture on the Triangle Congruence Theorems and Two Column Proofs in Plane/Solid Geometry. From reviewing Geometry, my understanding of the two columns proofs continues to improve with practice and deep understanding.

Test in 5 minutes. Length of video 50 minutes 😅

This channel is a diamond in the rough, thank you for the help.

Thank you so much for doing awesome job! My daughter got struggle on this topic and she said her teacher didn't teach well, but after my daughter watched this clip, she understood right away!!!! You're doing so great job!

When I return from school learning nothing.I can always count on you.This channel helped me a lot!

Your explanation is marvellous..lots of praise from India.

One of those few times ( or the only time) I actually went through a video about maths fully and understood most if not all the stuff. Thanks!

0:19 SSS≅ Postulate Explanation 0:30 SAS≅ Postulate Explanation (0:36 Clarification: "A" stands for a pair of congruent angles, one in each diagram, and "S" stands for a pair of congruent sides, one in each diagram) 0:38 ASA≅ Postulate Explanation (0:40 Clarification: "it has to be in order" means "the pair of congruent sides must be included (physically) between the two pairs of congruent angles in the diagram") 0:42 AAS≅ Postulate Explanation (0:49 Clarification: HL≅ Postulate (aka HLR≅, aka RHS≅) is not discussed but is often considered a viable 5th option.

unfortunately my boyfriend’s teacher sucks, so i had to watch this whole video to understand this 10th grade geometry. i’m still a freshmen but it doesn’t hurt to start early! And to be honest, this was the best understanding i could ever get. it’s so easy to him now since i re-teach it to him. thanks for the video! update: we broke up😃 i have a girlfriend now🙅🏽‍♀️

Bros still saving lives 🙌 THIS WAS SUPER EASY TO UNDERSTAND TYSMMM. Let's pray that I get a 90% on my test.

Bro may god bless you, my teacher has taught me geometry for 3 months and me and my friends haven't understood anything, but you helped me in less than 30 minutes, thank you so much.

Damn got a perfect score on my math test just by learning from this vid, thx man you're a life saver ♡´･ᴗ･`♡

I have to admit, my husband watched you for hours and hours and I got tired of hearing your voice but now that I have discovered why he watches you and how good you are, I love your voice....

Thanks for posting this. This was a million times easier to understand than my geometry book, and my geometry book didn't even explain it to me with a visual example, it just said some stuff, and expected me to understand it.

I just wanted to thank you. You cleared up my confusion by explaining clearly. Your explanations were simple but yet I learned a lot

If only all teachers taught this way

I’m not sure if he mentioned this in the video, but at my school we add Hypotenuse Leg into the mix. If the Triangle has two sides, and one angle, and the angle is a right angle (90 degrees) then you’ve got yourself a Hypotenuse Leg. Hope this helps!

Thank you. This is much clearer that listening to the whole quarter class.

thank you for this video. I needed for my geometry class

got my test tmr last minute procrastination this helped a lot

I learned more from you than my math teacher. Thank you so much for making this video

dude thank you- i missed a week of school and was so confused when i came back after thanksgiving break, nobody could explain it to me. not my teacher, not my friends, not my classmates, not my parents

I took geometry 3 years ago and I only just discovered this channel. I wish I discovered this channel sooner bc GEOMETRY WAS FREAKING ANNOYING. I understood it here far better than I did in school.

this video actually came in clutch

Thank you so much for this video! made me understand it more :)

Thank you, you're my life saver in geometry, physics, and biology and in other math lessons/topics.

youre the best thing that has ever happened to my life

Thank you, my teacher mostly just explains her thought process so this helped a lot

Tnx man you help me I past my exam

legit my teacher explained this for 3 days and i didn't get it but i understood it after only 5 minutes. Thank you !!

Its the way i asked many of my tutors and i understood none of them but this actually HELPED me.

Thx a lot man this really helped me prepare for my math test

Hi, I am a regents exam scorer, and this year I will be grading the Geometry Regents. I was watching this video to see how most kids are taught, and I see a couple of things wrong. 1st. Always state all your givens in one statement, or this year it will cause reductions. 2nd. Always put the full definition. When you were proving one of the problems at 24:37 you put vertical angles, when the correct statement is intersecting lines form congruent vertical angles. While you will not lose points, it is just good practice, and it prepares you for further steps, because proofs have more than 1 way, so lets say along the way you realize that there is an easier option, but you can't do it because you did not list the full definition.

This has made sense to me more than ever before. Thank you

test tmr on this and u saved me ! just learned more in 1hr than 1 month of learning this in school.

i literally love this. me and my bf are both in the 8 grade and doing ap subjects, this made us understand more. i adore this teacher, we both enjoyed it since we were fighting over who was right in the answers when the teacher asked a question. 😭 we both have a test tomorrow, wish us luck‼️‼️

Why is this guy better than my actual teacher? I legit understood all of this and before I watched this video I knew jack shit about sss,asa,etc.

Thanks a LOT! My congruence for my chapter understanding quadrilaterals is TERRIBLE so REALLY APPRECIATE this playlist.

God bless you! I’ve been struggling with these triangles

Thank you soo much!! This was a HUGE help! I really appreciate it. 😁

So I'm very very bad at math, and I, couldn't understand it when my teacher taught this, but in less than 20 minutes I could already understand it. And take note, I'm really bad at math and it takes me time before I could understand a lesson. So thank you for this wonderful video!❤

Thank you teacher!!! this really helps and it's my long test tomorrow!

Thank you and bless you and everyone else

Great video, the step by step tutorial shows me exactly how to do it correctly and there are many questions i can do to master the topic. I appreciate the effort and time you put into making these videos to help us!

Have me a test on this in about a week. Hope I can pick up everything by then 👐👐👐 (awesome video, really helping so far)

This man is a gift from god, im legit studying this a day before exam, i did not understand this while my teacher thought me .

Thank you so much for the explanation!! I understood everything that you said it is all clear now!

I'm literally so confused because what my teacher taught us deviates from this

THANK YOU VERY MUCH FOR THIS WONDERFUL VIDEO! I HOPE I PAST THE TEST TODAY :)

You are the best. You have taught me how to convert binary to hexadecimal and back and now my daughter and I are learning this from you.

Thank u very much for your wonderful teaching

Good thing that this video is allowed to be downloaded yay!

I have a geometry test tomorrow, this helped me a lot. Thank you so much.

Thankyou so much! I have midterms tomorrow and I’m learning more here than 4 months with my geo teacher!

Easy way for remembering! S is for side A is for angle Therefore SSS - Side Side Side SAS - Side Angle Side (Angle is in the middle) ASA- Angle Side Angle (Side in in the middle) AAS - Angle Angle Side (side is on the side) You can literally see how it works by remembering s is for side, a is for angle and looking at the structure of the three letters. Also I didn't watch the full 50 minutes of the video so I'm not sure if he mentioned this or not, but there is also another proof called RHS, standing for Right Angle, Hypotenuse and Side.

Thank you!!!!!!!! 😛

best teacher ever

Great review I recommend for any skeptical viewers; I’m from New York and it’s all good..

Im having trouble on my module's since the example weren't really clear this helped me, thanks a lot!

Your voice is so soothing, no homo.

summer geometry test is in 2 hours yikEs hope i do good

Omg at first I was literally crying fr and I'm so happy that I actually started running around and jumping thank u all my stress has been relieved thaaaaannnnnkkkkk uuuu!

soooo helpful! finally was able to finish my homework! test tomorrow but i think ill do fine now🥰 thank you!

Yo mate not to be rude or anything, but you don't mention the HL-therom

got a final exam tomorrow pray for me

This was so well explained. Thank you so much!

That was really helpful THANK YOU!

taught me more in a hour than 5 months in class

thanks for this video it really helped :)

u have no idea how much this helped thank u!!

Thanks! I finished my homework because of you!

The amount of views on this video shows how hard Triangle Congruence Theorem really is

Some one in 2019?

God bless you my man you came in clutch

you teach so well thank you!!
