Applying Angle Relationships

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. They are supplementary, meaning their measures 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 always equal in measure.

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. They are equal in measure when the lines are parallel.

Front

What are Same Side Exterior Angles?

Back

Same Side Exterior Angles are pairs of angles that lie on the same side of the transversal and outside the two lines. They are supplementary.

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. They are equal in measure when the lines are parallel.

Front

What are Corresponding Angles?

Back

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

Front

If angle 1 = 65°, what is the measure of angle 5 if they are Corresponding Angles?

Back

Angle 5 = 65°.

Front

If angle 3 = 75°, what is the measure of angle 4 if they are Vertical Angles?

Back

Angle 4 = 75°.

Front

If angle 2 = 110°, what is the measure of angle 6 if they are Alternate Interior Angles?

Back

Angle 6 = 110°.

Front

If angle 7 = 45°, what is the measure of angle 8 if they are Same Side Interior Angles?

Back

Angle 8 = 135°.
