Angle Relationships Assignment

Front

What are vertical angles?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

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

Back

The sum of the interior angles on the same side of the transversal is supplementary, meaning they add up to 180 degrees.

Front

How do you find the measure of an angle when given its vertical angle?

Back

The measure of an angle is equal to its vertical angle, so if you know one, you know the other.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

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

Front

If m∠1 = 30°, what is m∠3 if ∠1 and ∠3 are vertical angles?

Back

m∠3 = 30° because vertical angles are equal.

Front

What is the measure of corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal in measure.

Front

If m∠1 = 113°, what is the measure of its corresponding angle?

Back

The measure of the corresponding angle is also 113°.

Front

What is the definition of a transversal?

Back

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