| * A closed figure whose sides are all segments | polygon |
| * A pair of adjacent angles whose noncommon sides are opposite rays | linear pair |
| * A part of a line that consists of two endpoints | line segment |
| * Two angles whose measures have a sum of 180 | supplementary |
| * A unit of measure used in measuring angles and arcs | degree |
