Question

in an isosceles triangle ABC if angle B=90°,find angle A and angle C

Answer 1

Hey mate

Here is your answer

In isosceles triangle, two sides are equal.

AB= BC
angle A = angle C(Angles opposite to equal sides are equal.

Angle A + Angle B + Angle C = 180 (triangle Sum property)
Angle A + Angle A +90 = 180
Angle 2A = 90
Angle A = 45
Angle C = 45

Answer 2

I hope that the answer is A=45° , B=45°
