Do the sides of a triangle have to be equal
WebThere are 4 types of triangle. They all have 3 sides and are polygons. 1. Equilateral. Equilateral triangles have 3 equal sides and 3 equal angles of 60°. 2. Isosceles. … WebAn equilateral triangle is a regular polygon with n = 3 sides, interior angles of 60 degrees, and exterior angles of 120 degrees. For an equilateral triangle, we have a regular polygon with 3 sides (n = 3). The measure of each interior angle is 180 / 3 = 60 degrees. The measure of each exterior angle is 360 / 3 = 120 degrees.
