Parallel Lines and transversals

Front

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

Back

Corresponding angles are equal.

Front

Define alternate interior angles.

Back

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

Front

What is the measure of angle 8 if it is corresponding to angle 4 which measures 135°?

Back

Angle 8 measures 135°.

Front

Identify the alternate exterior angle to angle 3.

Back

The alternate exterior angle to angle 3 is angle 6.

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°.

Front

If angle 3 measures 45°, what is the measure of angle 5?

Back

Angle 5 measures 45° (alternate interior angles are equal).

Front

What type of angle pair are angles 1 and 8 if they are on the same side of the transversal and inside the parallel lines?

Back

Angles 1 and 8 are consecutive interior angles.

Front

If angle 4 measures 55°, what is the measure of angle 2?

Back

Angle 2 measures 125° (supplementary to angle 4).

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal.

Front

If angle 1 measures 44°, what is the measure of angle 3 if they are corresponding angles?

Back

Angle 3 measures 44°.
