Q. 12

# In , a line XY parallel to BC cuts AB at X and AC at Y. If BY bisects, thenA. BC =CYB. BC = BYC. BC CYD. BC BY

Given in ΔABC, XY || BC and BY is a bisector of XYC.

Since XY || BC,

YBC = BYC [alternate angles]

Now, in Δ BYC, two angles are equal.

Hence, two corresponding sides will be equal.

BC = CY
