This geometry video provides a basic introduction into triangles. It explains how to calculate the measure of an interior angle of a triangle as well as the exterior angle. The sum of all three interior angles is 180. The exterior angle is the sum of the two remote interior angles according to the exterior angle theorem. In addition, this video explains how to calculate the length of the midsegment of a triangle. It contains plenty of examples and practice problems.

16:33 stop right there. FEBD is a quadrilateral with two angles known (90 degrees defined by the altitude), one already calculated (from the larger triangle) and only one unknown, which turns out to be 110 degrees. This is equal to its opposite angle F at the crossing point of the altitudes.
