Determine If Two Lines Are Parallel From Angle Pair Relationships

Lines that never meet or cross and stay the same distance apart

• perpendicular lines

• parallel lines

• intersecting lines

• transversal

Find the measure of angle A.

• ∠A=82°

• ∠A=98°

• ∠A=180°

• ∠A=8°

Which lines are parallel if ∠3 and ∠5 are congruent?

• c ∥ d

• a ∥ b

• a ∥ c

• b ∥ c

Which theorem will justify your answer in Part A?

• Same side interior angles of parallel lines cut by a transversal are supplementary.

• Same side exterior angles of parallel lines cut by a transversal are supplementary.

• Alternate interior angels of parallel lines cut by a transversal are congruent.

• Alternate exterior angles of parallel lines cut by a transversal are congruent.
