Parallel Lines Cut By A Transversal Vocabulary

Vocabulary flashcards covering angle pairs and lines defined in geometry lessons on parallel lines cut by a transversal.

Transversal

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

Corresponding Angles

Two angles that lie on the same side of the transversal in corresponding positions.

Alternate Interior Angles

Interior angles that lie on the opposite sides of the transversal.

Alternate Exterior Angles

Exterior angles that lie on the opposite sides of the transversal.

Same Side Interior Angles (Consecutive Interior)

A pair of angles that are located on the same side of a transversal line and are positioned between the two lines that the transversal intersects.

Same Side Exterior Angles (Consecutive Exterior)

A pair of angles that are located outside two parallel lines and on the same side of the transversal that intersects them.

Supplementary Angles

Two or more angles whose sum is $180^\frac{1}{2}$.

Vertical Angles

Two angles whose sides form opposite rays.
