Different kinds of angles.
Angle relationships and how they can be used to apply algebraic concepts.

An angle is made up of two rays that have the same endpoint.
Each ray is called a side and the common endpoint is called the vertex.

Name an angle with three letters or only the vertex when no other angles are present.
The common endpoint of the two rays must be the middle letter.

Adjacent angles are two angles that share a common side.
The angle addition postulate requires that you have two adjacent angles.

An angle bisector is a ray that divides an angle into two congruent angles.
