Triangles.
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
All triangles have three sides
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.
