Transversal Angle Relationships

Front

What is the definition of Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of the transversal. They are equal in measure.

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of the transversal. They are equal in measure.

Front

What are Same Side Interior Angles?

Back

Same side interior angles are pairs of angles that lie between two parallel lines on the same side of the transversal. They are supplementary, meaning they add up to 180 degrees.

Front

What are Vertical Angles?

Back

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

Front

If Angle 1 = 40°, what is the measure of its corresponding angle?

Back

40°

Front

If Angle 3 = 75°, what is the measure of Angle 5 (alternate interior angle)?

Back

75°

Front

If Angle 2 = 110°, what is the measure of Angle 6 (same side interior angle)?

Back

70° (since they are supplementary, 180° - 110° = 70°).

Front

What is the relationship between Angle 4 and Angle 7 if they are vertical angles?

Back

Angle 4 = Angle 7.

Front

If Angle 1 = 27°, what is the measure of Angle 4 (corresponding angle)?

Back

27°.
