By angle sum property we know that the sum of all the angles of a triangle is 180° We know that all the sides of a triangle are equal. i.e all the angles of an equilateral triangle are equal. Let each angle be x. x + x + x = 180° 3x = 180° ⇒x = 60° Hence, we proved that all angle of a equilateral angle is 60°
