D is the midpoint of side BC of a triangle ABC.AD is bisected at a point E and BE produced cuts AC at the point X.Prove that - BE : EX = 3:1
Given:âABC where D is the mid point of BC, E is the mid point AD. BE produced meets AC at X.
To Prove:BE : EX = 3:1
Proof:
Comparing âBCX and âDCY:
BCX = DCY(Common)
BXC = DYC(Corresponding angles)
So,âBCX ∼ âDCY(AA Similarity test)
