Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are congruent angles?

Back

Angles that have the same measure.

Front

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

Back

They are equal.

Front

If m∠7 = 110°, what is m∠10 if lines a and b are parallel?

Back

70°.

Front

If m∠6 = 50°, what is m∠11 if lines a and b are parallel?

Back

130°.

Front

What is the relationship between alternate exterior angles when two lines are parallel?

Back

They are equal.

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees.

Front

What is a transversal?

Back

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