A triangle has three sides and three angles. The three angles always add to 180 degree. There are three special names given to triangles that tell how many sides (or angles) are equal.

There can be 32 or no equal sides/angles:

## Equilateral

• Three equal sides
• Threeequal angles, always 60°

## Isosceles

• Two equal sides
• Two equal angles

## Scalene

• No equal sides
• No equal angles

Triangles […]
