The triangle in which all the sides are equal is called equilateral triangle. The perimeter of a triangle is equal to the sum of all the sides.

Perimeter of an equilateral triangle= 3* measure of a side

Perimeter of an equilateral triangle= 3*7.5

Perimeter of an equilateral triangle= 22.5

All the angles of an equilateral triangle are equal because all the sides of this triangle are equal. All the angles of an equilateral triangle are acute angles. The measure of each angle of an equilateral triangle is 60
