Angle Relationships with Parallel Lines and a Transversal

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that are formed when two lines intersect. The angles are supplementary, meaning their measures add up to 180 degrees.

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie on the same side of the transversal and between the two parallel lines. They are supplementary.

What are same-side exterior angles?

Back

Same-side exterior angles are pairs of angles that lie on the same side of the transversal and outside the two parallel lines. They are also supplementary.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between the two parallel lines but on opposite sides of the transversal. They are equal in measure.

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

What is the transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points, creating various angle relationships.

Front

How do you identify congruent angles?

Back

Congruent angles are angles that have the same measure. They can be identified by comparing their degree measures.

What is the relationship between vertical angles?

Back

Vertical angles are pairs of angles that are opposite each other when two lines intersect. They are equal in measure.
