Question

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

Answer 1

Answer:

Given

AB AC

(Angles opposite to equal sides are equal

2C= ZB...(1)

In AABC,

∠ A + B + 2C = 180°(Angle sum property of triangles)

90°+ B+2C 180°(Given that ∠A = 90°)

90° + LB+ B 180°.......(From (1))

2 ∠B 90°

∠ B = 45

∠ B = 2C = 45°
