Transversal Warm-Up

Front

What are alternate interior angles?

Back

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

Front

What is the measure of angle 7 if it is given as 122°?

Back

Angle 7 measures 122°.

Front

What is the relationship between angles A and B if they are on opposite sides of the transversal and inside the two lines?

Back

Angles A and B are alternate interior angles.

Front

What is the relationship between angles A and B if they are on the same side of the transversal and in corresponding positions?

Back

Angles A and B are corresponding angles.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

How do you identify corresponding angles?

Back

Corresponding angles are located in the same position on two parallel lines in relation to a transversal.

Front

What is the sum of the measures of interior angles on the same side of a transversal?

Back

The sum of the measures of interior angles on the same side of a transversal is 180°.

Front

What is the relationship between two parallel lines cut by a transversal?

Back

When two parallel lines are cut by a transversal, alternate interior angles are equal, and corresponding angles are equal.

Front

What is the definition of a transversal?

Back

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

Front

If angle 3 is 58°, what is the measure of its alternate interior angle?

Back

The alternate interior angle to angle 3 is also 58°.
