Definitions An angle is the figure formed by two rays that share an endpoint. The rays are the sides. The shared endpoint is the vertex.

Measure A B C D EO

Postulate 3: Protractor Postulate

Postulate 4: Angle Addition Postulate

Definitions Congruent angles have the same measure. Adjacent angles share a vertex and side, but don’t overlap. The bisector of an angle splits the angle into two congruent angles.
