Practice Transversals and Parallel Lines

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are alternate exterior angles?

Back

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

Front

What are same side interior angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are always equal.

Front

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

Back

Alternate interior angles are equal.

Front

If angle 1 = 27°, what is the measure of angle 4 if angle 1 and angle 4 are corresponding angles?

Back

Angle 4 is also 27°.

Front

What is the relationship between same side interior angles when two parallel lines are cut by a transversal?

Back

Same side interior angles are supplementary, meaning they add up to 180°.

Front

How can you identify corresponding angles in a transversal situation?

Back

Corresponding angles can be identified as angles that occupy the same relative position at each intersection.
