Parallel Lines

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is the sum of the interior angles of a triangle?

Back

180°.

Front

Define alternate interior angles.

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is the relationship between supplementary angles?

Back

Two angles that add up to 180°.

Front

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

Back

They are equal.

Front

What is the measure of angle 4 if angle 1 = 27°?

Back

27° (because they are corresponding angles).

Front

What type of angle pair are angle 1 and angle 3 if they are on the same side of the transversal and add up to 180°?

Back

Supplementary angles.

Front

Name the alternate interior angle to angle 3 if angle 3 is 64°.

Back

Angle 5 (it is equal to angle 3).

Front

What is the measure of angle C if it is given that ∠C = 116°?

Back

∠C = 116°.
