Question

Triangle ABCis right triangle in which angle B is 90and AB=BC. find angle A and c

Answer 1

Hey friend,
Here is the answer you were looking for:

Given,
Angle B = 90°

AB = BC

So,
angle A = angle C ( opposite angles of equal lines are equal). ___ (I)

Then,
We know that,
Sum of 3 sides of a triangle = 180°

angle B + angle A + angle C = 180°
Using equation (I), we can write

angle B + angle A + angle A = 180°

90° + 2angleA = 180°

2 angle A = 180° - 90°

2angle A = 90°

angle A = 90° / 2

angle A = 45°

angle A = angle C

angle C = 45°

Hope this helps!!!

Answer 2

since it is Right angle isosceles triangle
if AB=AC then Angle A=angleC
by angle sum property value of A and C will b 45 degrees each
