Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What is the relationship between vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines intersect. They are always equal.

Front

Define alternate exterior angles.

Back

Alternate exterior angles are pairs of angles that are on opposite sides of a transversal and outside the two lines it intersects.

What are same side interior angles?

Back

Same side interior angles are pairs of angles that are on the same side of the transversal and inside the two lines it intersects.

What is the relationship between corresponding angles?

Back

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

Front

How do you determine if two lines are parallel using angle relationships?

Back

If a transversal intersects two lines and the alternate interior angles are equal, then the lines are parallel.

Front

What is the relationship between angles formed by a transversal and parallel lines?

Back

When a transversal intersects parallel lines, several angle relationships are formed, including alternate interior, alternate exterior, corresponding, and same side interior angles.
