Parts of an Angle
Other AnglesComplimentary Angles- two angles whose measurements add up to 90 degrees.
Supplementary Angles- two angles whose measurements add up to 180 degrees.
Vertical angles- Two angles, with the same measurement, that are created when two lines intersect.
DegreesAngles are measured in degrees. And can be written various ways.
A
B C
This angle can be written as < B since B is the vertex point or <ABC, a format that uses all three points in the angle for clarification.
All shapes have a degree measure. A circle measures 360 degrees.
A triangle has a measure of 180°. All the angle measures in the triangle add up to 180.

Adjacent angles- Angles that are next to each other. They have a common vertex and common side, but no other overlap.
