1.	ABC is a right angled triangle in which angle A =90°and AB=AC.find angle B and angle C
Answer» ∵ In ∆ABC,AB = AC∴ ∠B = ∠C ...(1)\| Angles opposite to equal sides of a triangle are equalIn ∆ABC,∠A + ∠B + ∠C = 180°\| Sum of all the angles of a triangle is 180°⇒ 90° + ∠B + ∠C = 180°\| ∵ ∠A = 90° (given)⇒ ∠B + ∠C = 90° ...(2)From (1) and (2), we get∠B = ∠C = 45°.
