Name | Description | Angle numbers |
Exterior | Exterior angles are on the outside of the transversed lines. | Angles 3, 4, 5 and 6 are exterior angles. |
Interior | Interior angles are between the transversed lines. | Angles 1, 2, 7 and 8 are interior angles |
Alternate | Alternate angles are on opposite sides the transversal. | Angles 1, 4, 5, and 8 are alternate to 2, 3, 6 and 7. |
Consecutive | Consecutive angles are adjacent angles on the same side of the transversal. | Angle pairs 1 and 8, 2 and 7 are consecutive. |
Corresponding | Corresponding angles are angles that are in the same positions relative to the two intersections. | Angle pairs 1 and 5, 2 and 6, 3 and 7, 4 and 8 are corresponding angles. |
Vertical | Vertical angles are opposite each other at an intersection. | Angle pairs 1 and 3, 2 and 4, 5 and 7, 6 and 8 are vertical angles. |
Alternate interior | Angle pairs that are interior angles and are opposite each other. | Angle pairs 1 and 7, 2 and 8 are alternate interior angles. |
Alternate exterior | Angle pairs that are exterior angles and are opposite each other. | Angle pairs 3 and 5, 4 and 6 are alternate exterior angles. |
