parallel lines,  | lines in a plane that do not intersect |
alternate exterior angles,  | pair of angles that lie on opposite sides of transversal, outside the other two lines |
alternate interior angles,  | pair of nonadjacent angles that lie on opposite sides of the transversal |
corresponding angles,  | angles on same side of transversal, same side of the other lines (same relative position) |
exterior angle,  | angle formed by one side of a polygon and the extension of an adjacent side |
interior angle,  | angle on the inner sides of two line cut by a transversal |
consecutive interior angle,  | pair of angles on the same side of a transversal and between two lines intersected by transversal |
transversal,  | line that intersects two or more lines |
| adjacent | next to or adjoining something |
skew,  | two lines that are not coplanar and do not intersect |
Postulate 13: Parallel Postulate,  | If there is a line and a point not on the line, then there is exactly one line through the point parallel to the given line. |
Postulate 14: Perpendicular Postulate,  | If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line. |
