Question

∆ ABC is right angledtriangle in which ∠A = 90⁰ and AB = AC . Find ∠B and∠C.​

Answer 1

Answer:

the angle will be of 45 and 45

Answer 2

Answer:

Since AB=AC,

So, △ABC is Right-angled isosceles.

∠B=∠C ...(angles opp. to equal sides are equal)

∠A+∠B+∠C=180°

...(angle - sum property of a triangle)

Substituting ∠B=∠C, ∠A=90°

90° +2∠B=180°

2∠B=180° –90°= 90°

∘

⇒∠B=45°

So, ∠C=∠B=45°
