Transversals

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal.

Front

What is the relationship between vertical angles?

Back

Vertical angles are congruent, meaning they have the same measure.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

What is the sum of the measures of consecutive interior angles?

Back

The sum of the measures of consecutive interior angles is 180 degrees.

Front

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

Back

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

Front

What is the measure of angle 4 if angle 2 is 70 degrees and they are corresponding angles?

Back

Angle 4 is also 70 degrees because corresponding angles are congruent.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are congruent when two parallel lines are cut by a transversal.

Front

If angle 1 is 50 degrees, what is the measure of angle 3 if they are alternate interior angles?

Back

Angle 3 is also 50 degrees because alternate interior angles are congruent.

Front

What is the relationship between consecutive interior angles when the lines are parallel?

Back

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