A triangle is a polygon with three sides and three angles. The three angles always add 180º.

There are three special names given to triangles that tell how many sides (or angles) are equal
  • Equilateral Triangle: Three equal sides and three equal angles, always 60º.
  • Isosceles Triangle: Two equal sides and two equal angles.
  • Scalene Triangle: No equal sides and no equal angles.
