Transversals & Angle Relationships

Front

What is a transversal?

Back

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

Front

What are alternate interior angles?

Back

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

Front

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

Back

When two parallel lines are cut by a transversal, alternate interior angles are congruent.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

Front

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

Back

When two parallel lines are cut by a transversal, same side interior angles are supplementary.

Front

What are corresponding angles?

Back

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

Front

What is the relationship between corresponding angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, corresponding angles are congruent.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line and are supplementary.

Front

If angle 1 and angle 2 are a linear pair, what is the sum of their measures?

Back

The sum of the measures of angle 1 and angle 2 is 180 degrees.

Front

True or False: Same side exterior angles are congruent when two parallel lines are cut by a transversal.

Back

False. Same side exterior angles are not congruent; they are supplementary.
