Transversals & Angles

Front

What is a transversal?

Back

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

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal.

Front

What is the relationship between alternate exterior angles?

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal.

Front

Define vertical angles.

Back

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

Front

What is the sum of supplementary angles?

Back

The sum of supplementary angles is 180 degrees.

Front

What is the sum of complementary angles?

Back

The sum of complementary angles is 90 degrees.

Front

If angle 3 is 70 degrees, what is the measure of its alternate interior angle?

Back

The alternate interior angle is also 70 degrees if the lines are parallel.

Front

Identify the angle pair: Angle 2 and Angle 6 are...

Back

Corresponding angles.

Front

What is the relationship between angle pairs formed by a transversal?

Back

Transversals create several angle pairs: alternate interior, alternate exterior, corresponding, and vertical angles.
