Transversals & Angles

Front

What is a transversal?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are on the same side of the transversal and in corresponding positions.

Front

What are vertical angles?

Back

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

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the relationship between alternate exterior angles?

Back

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

Front

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

Back

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

Front

If angle 3 is 70 degrees, what is the measure of angle 5 if they are alternate interior angles?

Back

Angle 5 is also 70 degrees because alternate interior angles are equal.

Front

What is the sum of the measures of supplementary angles?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

If angle 1 is 50 degrees, what is the measure of angle 7 if they are vertical angles?

Back

Angle 7 is also 50 degrees because vertical angles are equal.
