This video has Proof of Basic Proportionality Theorem (BPT) | Thales Theorem which is "when a line is drawn parallel to one of the sides of a triangle, it divides other two sides in equal ratio"
Today in this session we will learn 3 important properties as well as Proof of Basic Proportionality Theorem.
Property 1: Triangles drawn between two parallel lines with same base have equal areas.
Property 2: Ratio of areas of triangles with equal height is equal to the ratio of their bases.
Property 3: A line parallel to one side of a triangle divides the other two sides in equal proportion.
Basic Proportionality Theorem - “When a line is drawn parallel to one of the sides of a triangle, it divides other two sides in equal ratio".
