In a triangle ABC, D is a point on BC such that AD is the internal bisector of `angle A`. Let `angle B = 2 angle C` and CD = AB. Then `angle A` is

In a triangle ABC , AB = AC and angle A = 36^(@) If the internal bisector of angle C meets AB at D . Prove that AD = BC.

Let Delta ABC be equilateral. If D is a point on BC and AD is the internal bisector of angle A . Using Angle Bisector Theorem, (BD)/(DC) is ………….

ABC is a triangle with angle B greater than angle C . D and E are points on BC such that AD is perpendicular to BC and AE is the bisector of angle A. Complete the relation angle DAE = 1/2 [(…..) - angle C]

If the bisector of angle A of triangle ABC makes an angle theta with BC, then sin theta is
