Question

In the adjoining diagram, AB=AC , BX=CY and KX//AY then prove that: triangle XKP perpendicular triangle YCP.​

Answer 1

Answer:

ABC is an isosceles triangle. Since AB = AC, angle B = angle C, so their half angles will be equal.

In triangles ABX and ACY,

Angle ABX (half of angle B) = and ACY (half of angle C)

AB = AC, and

A is common to both,

So the two triangles are congruent. Therefore BX = CY.
