Показать описание
Converse of Basic Proportionality Theorem - Converse of Thales Theorem - This is a very important theorem in triangle geometry. Converse of Thales theorem or basic proportionality theorem is just opposite of Thales theorem / basic proportionality theorem.

Converse of Basic Proportionality Theorem / Converse of Thales Theorem:
If a line divides the any two sides of a triangle in the same ratio, then the line must be parallel to the third side.

With the help of converse of basic proportionality we can show two lines parallel and further we can find hidden angles and even sides etc.

I hope this triangle geometry tutorial was helpful for you for giving the proof of Converse of Basic Proportionality Theorem / Converse of Thales Theorem:
