Parallel Lines and Transversals Independent Practice

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines.

Front

What are corresponding angles?

Back

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

Front

What are vertical angles?

Back

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

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two parallel lines; they are supplementary.

Front

What is the relationship between alternate exterior angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

If ∠1 and ∠3 are supplementary, what does that mean?

Back

Their measures add up to 180 degrees.

Front

How do you find the value of x in angle problems?

Back

Set up an equation based on the relationships between the angles and solve for x.

Front

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

Back

180 degrees.

Front

If two angles are complementary, what is their relationship?

Back

Their measures add up to 90 degrees.

Front

What is the definition of a transversal?

Back

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