Question

In ΔABC, a line XY parallel to BC cuts AB at X and AC at Y. If BY bisects ΔXYC, then
A. BC =CY
B. BC = BY
C. BC≠ CY
D. BC≠ BY

Answer 1

Answer:

in triangle ABC, a line XY parallel to BC cuts AB at X and AC at Y if BY in triangle ABC, a line XY parallel to BC cuts AB at X and AC at Y. if BY bisects angle XYC, then show that BC = CY. Hence, in triangle BYC, BC = CY. Hence, in triangle BYC, BC = CY (opposite angles of equal sides are equal in a triangle).

Answer 2

Answer:

C. BC≠ CY
