Corresponding, Alternate Interior, Alternate Exterior Angles

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are same side interior angles?

Back

Angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary (add up to 180 degrees).

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate exterior angles?

Back

They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about the same side interior angles?

Back

They are supplementary (add up to 180 degrees).

Front

Find the measure of the missing angle if one angle is 83 degrees and they are same side interior angles.

Back

97 degrees (180 - 83 = 97).

Front

Find the measure of the missing angle if one angle is 73 degrees and they are alternate interior angles.

Back

73 degrees (they are equal).
