Transversals

Front

What are transversals?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are 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 alternate exterior angles?

Back

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

Front

What are vertical angles?

Back

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

Front

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

Back

Corresponding angles are congruent.

Front

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

Back

Alternate interior angles are congruent.

Front

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

Back

Consecutive interior angles are supplementary (add up to 180 degrees).

Front

If angle A is 70 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle is also 70 degrees.

Front

If angle 1 and angle 2 are vertical angles, and angle 1 measures 45 degrees, what is the measure of angle 2?

Back

Angle 2 also measures 45 degrees.
