Lines and Angles Practice

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 corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

If two angles are supplementary, what is the sum of their measures?

Back

The sum of the measures of two supplementary angles is 180 degrees.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal.

Front

If m∠1 = 30°, what is m∠3 if ∠1 and ∠3 are corresponding angles?

Back

m∠3 = 30°.

Front

What is the definition of supplementary angles?

Back

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

Front

Identify the angle relationship: If angle 2 and angle 6 are on the same side of the transversal and inside the parallel lines, what are they called?

Back

They are called same side interior angles.

Front

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

Back

Angle 4 = 27°.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

Alternate exterior angles are equal.

Front

If angle 1 and angle 5 are vertical angles, what can be said about their measures?

Back

Angle 1 = Angle 5.
