Angle `A ,\ B ,\ C` of a triangle `A B C` are equal to each other. Prove that ` A B C` is equilateral.

Explanation

To prove that triangle ABC is equilateral given that angles A, B, and C are equal, we can follow these steps:

### Step 1: State the Given Information
We are given that:
- Angle A = Angle B = Angle C

### Step 2: Use the Property of Angles in a Triangle
Since the sum of the angles in any triangle is 180 degrees, we can write:
