Question

Prove BPT theorem briefly with neat figure

Answer 1

Answer:

To verify the basic proportionality theorem by using parallel lines board, triangle cut outs. If a line is drawn parallel to one side of a triangle, to intersect the other two sides at distinct points, the other two sides are divided in the same ratio.

Answer 2

Answer:

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. ..

Given: In ΔABC, DE is parallel to BC

To Prove: \frac{AD}{BD} = \frac{AE}{CE}
