Angles Formed by a Transversal

Front

What are Same-side Interior Angles?

Back

Same-side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two lines.

Front

What is the measure of ∠I if it is given as 105°?

Back

∠I = 105°.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie on opposite sides of the transversal and between the two lines.

Front

What are Alternate Exterior Angles?

Back

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

Front

If m∠1 = 30°, what is m∠3 if they are corresponding angles?

Back

m∠3 = 30°.

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 sum of the measures of same-side interior angles?

Back

The sum of the measures of same-side interior angles is 180°.

Front

How do you identify corresponding angles?

Back

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

Front

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

Back

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

Front

What is the definition of a transversal?

Back

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