    Step-by-step explanation:

    In an equilateral triangle, all the three sides are equal as well as all the angles are equal. Let the angles be x.

    We know that the sum of angles of a triangle is equal to 180 degrees. It means that,

    x+x+x=180

    3x=180

    x=60°

    Hence, if a triangle is an equilateral triangle, then the triangle has exactly three 60°  angles. Hence, △ABC is an equilateral triangle
