Parallel Lines Cut by Transversals Vocab Flashcard

Front

What is a Linear Pair?

Back

A pair of adjacent angles whose non-common sides are opposite rays, and they are supplementary.

Front

What are Corresponding Angles?

Back

Angles in the same position on different lines when a transversal crosses them.

Front

What are Alternate Exterior Angles?

Back

Angles that lie outside the two lines and on opposite sides of the transversal.

Front

What is a Linear Pair? (repeated for emphasis)

Back

Angles that are next to each other and add up to 180 degrees, formed when two lines intersect.

Front

What are Same-Side Exterior Angles?

Back

Angles outside the lines that lie on the same side of the transversal and are supplementary when lines are parallel.

Front

What are Alternate Interior Angles?

Back

Angles that lie between the two lines and on opposite sides of the transversal.

Front

What are Consecutive Interior Angles?

Back

Angles that lie between the two lines and on the same side of the transversal.

Front

What is a Transversal?

Back

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

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What is the relationship between Parallel Lines and Corresponding Angles?

Back

When two parallel lines are cut by a transversal, corresponding angles are equal.
