Parallel Lines Angle Vocabulary

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Define Alternate Interior Angles.

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. They are equal in measure.

Explain Same Side Interior Angles.

Back

Same side interior angles are pairs of angles that lie between two parallel lines on the same side of a transversal. They are supplementary, meaning their measures add up to 180 degrees.

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

How do you find Corresponding Angles in a transversal situation?

Back

To find corresponding angles, look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.

What is the significance of the Transversal in angle relationships?

Back

A transversal is a line that intersects two or more lines, creating various angle relationships such as corresponding, alternate interior, and same side interior angles.
