Parallel Lines Cut by a Transversal II

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They 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 angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that are on opposite sides of the transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are angles that are on opposite sides of the transversal and outside the two lines.

Front

What are consecutive interior angles?

Back

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

Front

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

Back

Corresponding angles are equal.

Front

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

Back

Alternate interior angles are equal.

Front

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

Back

Consecutive interior angles are supplementary (add up to 180 degrees).

Front

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

Back

The measure of the angle is equal to the measure of its corresponding angle.
