Transversal Angle Relationships

Front

What is the relationship of the angles formed by two parallel lines cut by a transversal that are opposite each other and not adjacent?

Back

Vertical Angles are equal.

Front

What is the angle relationship between two angles that are on opposite sides of the transversal and inside the two parallel lines?

Back

Alternate Interior Angles are equal.

Front

What is the angle relationship between two angles that are on the same side of the transversal and inside the two parallel lines?

Back

Same-Side Interior Angles are supplementary.

Front

What is the angle relationship between two angles that are on the same side of the transversal and outside the two parallel lines?

Back

Alternate Exterior Angles are equal.

Front

What is the angle relationship between two angles that are on the same side of the transversal and in corresponding positions?

Back

Corresponding Angles are equal.

Front

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

Back

Alternate Exterior Angles are equal.

Front

What is the sum of the measures of same-side interior angles when two parallel lines are cut by a transversal?

Back

The sum is 180 degrees.

Front

What is the relationship of angles that are formed by two intersecting lines?

Back

The angles are Vertical Angles and are equal.

Front

If angle 1 and angle 2 are corresponding angles, what can be concluded if the lines are parallel?

Back

Angle 1 is equal to Angle 2.

Front

What is the relationship of angles that are on opposite sides of the transversal and outside the two parallel lines?

Back

They are Alternate Exterior Angles and are equal.
