This resource has been contributed by Winpossible, and can also be accessed on their website by clicking here - Identify Special Angle Pairs.

In this section, you'll learn with the help of video lesson how to identify special angle pairs i.e. angles formed when a transversal cuts (or intersects) parallel lines. E.g. the most important angles are called alternate interior angles, alternate exterior angles and corresponding angles. The basics to remember:

In this section, you'll learn with the help of video lesson how to identify special angle pairs i.e. angles formed when a transversal cuts (or intersects) parallel lines. E.g. the most important angles are called alternate interior angles, alternate exterior angles and corresponding angles. The basics to remember:

- Interior means ‘Between’ the parallel lines.
- Exterior means ‘Outside’ the parallel lines.
- Alternate means "alternating sides" of the transversal

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
