| intersection ( a sets of _ common to _ or more _ figures) | A set of points common to two or more geometric figures. |
| adjacent angles ( two angles that lie in the same _ and have a common _ and a common _ but have no common _ points ) | Two angles that lie in the same plane and have a common vertex and a common side but have no common interior points. |
