Answer 1

Step-by-step explanation:

Construction:

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

Draw EF ⟂ AD

and

DG⟂ AE

and

join the segments BE and CD.

Note that ΔDBE and ΔECD have a common base DE and lie between the same parallels DE and BC. Also, we know that triangles having the same base and lying between the same parallels are equal in area.

Hence Proved.
