## Types of Triangles

There are 6 types of TRIANGLES! Let me show you.

## I'm an ACUTE triangleI have 3 ACUTE angles. | ## I'm a RIGHT triangleI have 1 RIGHT angle and 2 ACUTE angles. | ## I'm an OBTUSE triangleI have 1 OBTUSE angle and 2 ACUTE angles. |

## I'm a SCALENE triangleI have 0 CONGRUENT sides and 0 CONGRUENT angles. | ## I'm an ISOSCELES triangleI have 2 CONGRUENT sides and 2 CONGRUENT angles. | ## I'm an EQUILATERAL triangleI have 3 CONGRUENT sides and angles. |

## The Case of the MISSING angles

## Case Details

- ALL the angles of a quadrilateral = 360 degrees
- ALL the angles of a triangle = 180 degrees
