| Alternate Exterior Angles | Two angles that lie outside of the two lines cut by the transversal and on opposite sides of the transversal. |
| Alternate Interior Angles | Two angles that lie inside of the two lines cut by the transversal and on opposite sides of the transversal. |
| Coincident | The lines which are graphs of two equivalent linear equations. |
| Consecutive Interior Angles | Two angles that lie inside of the two lines cut by the transversal and on the same side of the transversal. |
| Contrapositive | If not q then not p; true if and only if the conditional statement is true. |
| Corresponding Angles | Two angles on the same side of the transversal, one is exterior and the other is interior of the lines cut by the transversal. |
| Intersecting | Coplanar lines that have exactly one point in common. |
| Negation | Denial of a statement (not p). |
| Oblique | Intersecting lines that do not form right angles. |
| Parallel Lines | Coplanar lines that do not intersect. |
| Parallel Planes | Planes that do not intersect. |
| Parallel Vectors | Vectors that have the same or opposite directions. |
| Skew | Two lines that are not coplanar. |
| Transversal | A line that intersects two or more coplanar lines at different points. |
| Vector | A quantity that has both direction and magnitude (or length). |
