Angles on a Parallel Line

Corresponding angles are angles that are facing the same way.
This is the F shaped angle.
These angles are equal.

For Example - if one is 60⁰ then the other is going to be 60⁰

Corresponding Angles

Alternate angles are angles that are face two different ways and are on top of each other.
This is the Z shaped angle.
These angles are equal.

For Example - if one is 50⁰ then the other is 50⁰

Alternate Angles

Allied or Co-Interior angles are angles that are in the same space.
This is the C shaped angles.
These angles add up to 180.

For Example - if one of the angles were 70⁰ then the other angle will be 110⁰

Allied or Co- Interior Angles

Opposite angles are angles that are exactly opposite to it.
This is the X shaped angle.
These angles are equal.

For example - if one angle is 20⁰ then the other angle is 20⁰

Opposite Angles
