Transversals & Parallel Lines

Front

What are Transversals?

Back

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

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 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 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 are Alternate Exterior Angles?

Back

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

Front

If angle P measures 60 degrees, what is the measure of angle C if they are corresponding angles?

Back

Angle C measures 60 degrees.

Front

If angle P measures 60 degrees, what is the measure of angle C if they are alternate interior angles?

Back

Angle C measures 120 degrees.

Front

What is the sum of the interior angles on the same side of a transversal?

Back

The sum of the same side interior angles is 180 degrees.

Front

If ∠J=75°, what is the measure of the angle that is corresponding to it?

Back

The corresponding angle also measures 75°.
