ABC is a right angled triangle find b and c

Question: ABC is a right-angled triangle in which A = 90° and AB = AC. Find B and C.
Solution: Given : A = 90° and AB = AC
⇒ B = C (Angles opposite to the equal sides)
We know, A + B + C = 180° (Since the sum of the interior angles of the triangle = 180°)
Therefore, 90° + 2B = 180°
⇒ B = C = 45°
