Q.1 ABCD is a parallelogram. AB is produced tobisects BC. |
|
Answer» Given, ABCD is a parallelogram. BE = AB To show, ED bisects BC Proof: AB = BE (Given) AB = CD (Opposite sides of ||gm) ∴ BE = CD Let DE intersect BC at F. Now, In ΔCDO and ΔBEO, ∠DCO = ∠EBO (AE || CD) ∠DOC = ∠EOB (Vertically opposite angles) BE = CD (Proved) ΔCDO ≅ ΔBEO by AAS congruence condition. Thus, BF = FC (by CPCT) Therefore, ED bisects BC.
