Question

∠A = 90° , ∠B = ∠C , ∠B = ? , ∠C = ?

Answer 1

Answer:

angle B is equal to 45 and angle C is equal to 45

Answer 2

Step-by-step explanation:

AB=AC

[Given ]

∠A=90°

∴ ∠C=∠B

[ Angles opposite to equal sides are equal ] ---- ( 1 )

In △ABC,

∠A+∠B+∠C=180°

[ Angles sum property of triangles ]

⇒ 90° +∠B+∠C=180°

⇒ 90 ° +∠B+∠B=180°

[ From ( 1 ) ]

⇒ 2∠B=90°

⇒ ∠B=45°

∴ ∠B=∠C=45°(Ans).
