Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

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

Back

They are equal.

Front

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

Back

They are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the same-side interior angles?

Back

They are supplementary (add up to 180 degrees).

Front

Solve for x: m<1 = 125 degrees, m<6 = 5x. What is x?

Back

x = 25.
