Question

in figure of triangle ABC ad is bisector of angle BAC and AD perpendicular to BC show that angle DAE = 1/2 (angle C - Angle B)

Answer 1

Hello user

Since,

In the triangle ABC ad is bisector of angle BAC and AD perpendicular to BC

So , angle DAE = 90° - B .....

Also, Angle CAD = C - 90°

Since, angle DAE = Angle CAD, we get

2 × angle DAE = C - D

angle DAE = 1/2(C - D)
