Copy of Transversal Intersects Parallel Lines

Image
A line that crosses two lines is called a TRANSVERSAL.
If we draw two parallel lines and then draw a line transversal through them, we will get eight different angles.
Image
Interior/Exterior Angles in a Transversal.
The angles between the parallel lines are called the interior angles.
Image
The angles that are on the outside of the parallel lines are called exterior angles.

Exterior Angles

Exterior Angles
Alternate/Corresponding Angles in a Transversal

Example of a corresponding angle

Example of a corresponding angle
Corresponding angles are matching angles on the same side of the transversal. Study the image below to see all corresponding angles in a transversal.
Image
Image
Alternate angles are matching angles that are across from each other on the transversal.

Use the Interactive and the chart below to learn the locations of interior, exterior, corresponding and alternate angles in a transversal.
