Given : Angles A, B, C of a triangle ABC are equal to each other.

To prove : Δ ABC is equilateral.

 

We have,

∠A = ∠B = ∠C

Now,

∠A = ∠B

BC = AC ………….(1)

[sides Opposite to equal angles are equal]

 

∠B = ∠C

AC = AB ……………(2)

[sides Opposite to equal angles are equal]

From the eq 1 and 2 , we get

AB = BC = AC

Therefore, Δ ABC is equilateral.

Hence, proved
