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.
