### Show that the angles of an equilateral triangle is 60

For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles. Since, we know, that the sum of all angles of any triangle be 180°. Let each angle be a. Thus, Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.
