Question

M is the midpoint of the side DC of a parallelogram ABCD . Line BM interests seg AC at point L and line AD at point E
Prove that, EL=2BL

Answer 1

Given ;-

∆ EDM and ∆ BCM are similar.

MD=CM => BC = DE,

as AD = BC,

AE = 2 BC

Similarily,,

ΔACL & ΔAEL are similar.

EL / BL = AE / BC = 2


So EL = 2 BL
