Terms | Definitions |
|---|---|
 Parallel Lines | Coplanar, equidistant, non-intersecting lines |
| Parallel Planes | Equidistant, non-intersecting planes |
| Skew Lines | Non-coplanar, non-intersecting lines |
| Transversal | Line that intersects two or more lines in a plane at different points |
| Interior Angles | Inside angles of two lines intersected by a transversal |
| Exterior Angles | Outside angles of two lines intersected by a transversal |
| Alternate Interior Angles | Inside angles of two line intersected by a transversal and on opposite sides of the transversal |
| Alternate Exterior Angles | Outside angles of two lines intersected by a transversal and on opposite sides of the transversal |
| Same Side Interior Angles | Inside angles of two lines intersected by a transversal and on the same side of the transversal |
| Corresponding Angles | Pair of angles formed by two lines and a transversal consisting of an interior angle and an exterior angle that have different vertices and that lie on the same side of the transversal |
| Corresponding Angles Postulate | Two parallel lines cut by a transversal create corresponding angles that are congruent. |
| Alternate Interior Angles Theorem | Two parallel lines cut by a transversal create alternate interior angles that are congruent. |
| Same Side Interior Angles Theorem | Two parallel lines cut by a transversal create consecutive interior angles that are supplementary. |
| Alternate Exterior Angles Theorem | Two parallel lines cut by a transversal create alternate exterior angles that are congruent. |
