1. Ch 1.4

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

3.  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.

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

6.  Zero:  Acute:  Right:  Obtuse:  Straight:

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

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