| alternate exterior angles | Two angles that are formed by two lines and a transversal and lie outside the two lines on the opposite sides of the transversal. |
| alternate interior angles | Two angles that are formed by two lines and a transversal and lie between the two lines on the opposite sides of the transversal. |
| converse | The statement formed by switching the hypothesis and the conclusion of an if-then statement.. |
| corresponding angles | Two angles that are formed by thwo lines and a transversal and occupy corresponding positions. |
| image | The new figure that results from the transformation of a figure in a plane. |
| line perpendicular to a plane | A line that intersects a plane in a point and is perpendicular to every line in the plane that intersects it. |
| parallel lines | Two lines that lie in the same plane and do not intersect. |
| parallel planes | Two planes that do not intersect. |
| perpendicular lines | Two lines that intersect to form right angles. |
| same-side interior angles | Two angles that are formed by two lines and a transversal and lie between the two lines on the same side of the transversal. |
| skew lines | Two lines that do not lie in the same plane and do not intersect. |
| transformation | An operation that maps or moves a figure onto an image. This can be a dilation, reflection, rotation or translation. |
| translation | A transformation that slides each point of a figure the same distance in the same direction. |
| transversal | A line that intersects two or more coplanar lines at different points. |
