Transversals and Parallel Lines Mixed Review

Front

What are transversals?

Back

Transversals are lines that intersect two or more other lines at distinct points.

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 are alternate interior angles?

Back

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

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

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

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

Back

The alternate interior angles are congruent.

Front

If ∠A and ∠B are vertical angles, what can be said about their measures?

Back

The measures of vertical angles are equal.

Front

What is the sum of the measures of angles on a straight line?

Back

The sum of the measures of angles on a straight line is 180 degrees.

Front

If two angles are supplementary and one angle measures 45 degrees, what is the measure of the other angle?

Back

The other angle measures 135 degrees.
