# Triangles

A triangle is a shape that has three sides and three angles.

There are three types of triangles.

- Equilateral Triangle: All the sides of the triangle are the same lengths.
- Isosceles Triangle: Two of the sides are the same.
- Scalene Triangle: All three sides of the triangle are different lengths.

A right triangle can be both an isosceles triangle and a scalene triangle but can't be an equilateral triangle. This is because all the angles of the equilateral triangle are 60 degrees.
