Question

In a right-angled triangle, the angles other than the right angle are

(a) obtuse (b) right (c) acute (d) straight

Answer 1

(c) acute

In right angled ∆ABC

∠B = 90^o

∠A + ∠B + ∠C = 180^o [angle sum property of a triangle]

Hence, in a right angled triangle, the angles other than the right angle are acute.
