Question

how to find angle B and angle C in a ABC right angle triangle if angle A is 90 and AB = AC​

Answer 1

HEYA !!!

We know that the sum of angle of triangle is 180°...if angle A is 90° then,,180-90= 90. AB=AC therefore,, angle B =angle C= 45° .

Hope it helps you

Answer 2

Answer:

Given AB = BC

so by using property If opp.sides are equal than their angles are also equal

90°+x°+x°= 180

90°+2x= 180

2x=90

x=45°
