Question

give a proof of basic proportionality theorem

Answer 1

Basic Proportionality Theorem and Equal Intercept Theorem. Basic Proportionality Theorem: If a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion. Let's not stop at the statement, we need to find a proof that its true.

Answer 2

statement of basic proportionality theorem is if a line is drawn parallel to one side of a triangle intersecting the other 2 sides in distinct points divides other 2 sides in the same ratio.
