Question

ABC is a right angled triangle in which angle A=90 degree and AB=AC.find angle B and angle C.​

Answer 1

The sum of measure of all angles of a triangle is 180°.

as AB = BC ....the given triangle is an isosceles triangle.

Let AB = BC = x

angle A + angle B + angle C = 180°

90 + x + x = 180°

90 + 2x = 180°

2x = 180 - 90

2x = 90

x = 90/2

x = 45°

therefore,angle B and angle C will be of 45°.
