Transversal Angle Relationships

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of 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 are on opposite sides of the transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

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

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

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

Back

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

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

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

Back

Same-side interior angles are supplementary (add up to 180 degrees) when two parallel lines are cut by a transversal.

Front

If angle 1 is 70 degrees, what is the measure of angle 5 if angle 1 and angle 5 are corresponding angles?

Back

Angle 5 is also 70 degrees.

Front

If angle 3 is 110 degrees, what is the measure of angle 4 if angle 3 and angle 4 are alternate interior angles?

Back

Angle 4 is also 110 degrees.
