ABC is a right angle triangle in which angle a= 90° and ab AC find angle b and c

Answer»

Answer:

Since AB = AC,

So, △ABC is Right-angled isosceles.

∠B=∠C

...(angles OPP. to equal sides AREEQUAL)

∠A+∠B+∠C=180 ∘

..(angle - SUM property of a triangle)

∠B=∠C, ∠A=90°

90 ∘ +2∠B=180 ∘

2∠B = 180∘ – 90 ∘ = 90∘

⇒∠B=45 °
