Parallel Lines and Transversals Retake

Front

What are parallel lines?

Back

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

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 similar positions at each intersection where a transversal crosses two lines.

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 are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is a linear pair of angles?

Back

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

Front

What are consecutive interior angles?

Back

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

Front

How do you find the measure of an angle when given its corresponding angle?

Back

If two lines are parallel and a transversal intersects them, corresponding angles are equal.

Front

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

Back

Alternate exterior angles are congruent when two lines are parallel.

Front

What is the sum of the measures of angles in a linear pair?

Back

The sum of the measures of angles in a linear pair is 180 degrees.
