Question

ABC is a right angle triangle in which angle A is equal to 90 degree and a b is equal to a c find angle b & angle c

Answer 1

∠C = ∠B ( if two sides of a triangle are equal, the angles opposite to these sides are equal.

Therefore,

∠A + ∠B + ∠C = 180°

90° + x + x = 180°

90° + 2x = 180°

2x = 180° - 90°

2x = 90°

x = 45°

Therefore,

∠B = 45°

∠C = 45°
