Angles on parallel lines

The straight line that cuts a pair of parallel lines is called

• an angle

• a ray

• a transversal

• a point

Corresponding angles in the same position on parallel lines are

• equal

• supplementary

• vertically opposite

• complementary

Which of the following statements is ALWAYS TRUE when parallel lines are cut by a transversal?

• The sum of the degree measure of corresponding angles is 180°.

• Corresponding angles are supplementary.

• Vertically opposite angles are acute

• The sum of co interior angles is 180°

In the diagram of parallel lines cut by a transversal, shown above, which of the following statements is false?

• ∠3 and ∠4 are vertically opposite angles.

• ∠5 and ∠8 are corresponding angles.

• All of the statements are false

• ∠3 and ∠6 are alternate angles.

In the figure, the angles are formed by a transversal and two parallel lines. Explain why <5 and <2 are equal.

• They are alternate angles

• They are corresponding angles

• They are vertically opposite angles

• They are supplementary angles
