Question -

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



Answer -

It is given that

AB = AC

C = B (Angles opposite to equal sides are also equal)

In ΔABC,

A + B + C = 180º (Angle sum property of a triangle)

90º + B + C = 180º

90º + B + B = 180º

2 B = 90º

B = 45º

B = C = 45º
