Question

If all the three angles of a triangle are equal, then each one of them is equal to
A. 90°
B. 45°
C. 60°
D. 30°

Answer 1

Given : All the three angles of a triangle are equal.

Let, the angles of ∆ABC be ∠A , ∠B  and  ∠C.

∠A = ∠B = ∠C [Given]

We know that, the sum of  three angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

∠A + ∠A + ∠A = 180°

3∠A = 180°

∠A = 180°/3

∠A = 60°

Therefore,

∠A = ∠B = ∠C = 60°

Hence,each one of them is equal to 60°.

Among the given options option  (C) 60° is correct.
