Question

ABC is a right angled triangle in which ∠ A = 90° and AB = AC. Find ∠ B and ∠ C.​

Answer 1

if the both sides are same then the angels are also same.

so, angle B = angle C

so ,90° + B + C = 180° [ linear pair]

So B and C are same so we take their value as ‘x’

so, 90° + x + x= 180

2x = 180-90

2x = 90

x = 45

so, the values of angle B and C are 45°
