Angles/Transversal practice

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that lie between two parallel lines on the same side of a transversal. They are supplementary (add up to 180 degrees).

Front

If angle 5 is 70 degrees, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 is also 70 degrees because alternate interior angles are equal.

Front

If angle 1 is 50 degrees, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 is also 50 degrees because corresponding angles are equal.

Front

Which angles are NOT congruent to angle 5 if angle 5 is 60 degrees?

Back

Angles that are not congruent to angle 5 are any angles that do not measure 60 degrees.

Front

What is the relationship between same side interior angles?

Back

Same side interior angles are supplementary, meaning their measures add up to 180 degrees.

Front

Identify a pair of alternate exterior angles given two parallel lines cut by a transversal.

Back

For example, if angle 2 and angle 8 are on opposite sides of the transversal and outside the parallel lines, they are alternate exterior angles.

Front

If angle 3 is 120 degrees, what is the measure of angle 5 if they are same side interior angles?

Back

Angle 5 is 60 degrees because same side interior angles are supplementary (120 + 60 = 180).
