WU Day 053 Parallel Lines and Transversals

What is the definition of parallel lines?

• Lines that never intersect

• Lines that intersect at multiple points

• Lines that intersect at one point

• Lines that are perpendicular to each other

If two parallel lines are cut by a transversal, what is the sum of the interior angles on the same side of the transversal?

• 360

• 270

• 90

• 180

If two parallel lines are cut by a transversal, what is the sum of the exterior angles on the same side of the transversal?

• 90

• 270

• 180

• 360

What is the alternate interior angles theorem?

• Alternate interior angles are always equal to 90 degrees.

• Alternate interior angles are supplementary.

• Alternate interior angles are always acute angles.

• Pairs of alternate interior angles are congruent.

What is the alternate exterior angles theorem?

• Pairs of alternate exterior angles are congruent.

• Alternate exterior angles are supplementary.

• Alternate exterior angles are parallel.

• Alternate exterior angles are equal to 90 degrees.

What is the corresponding angles theorem?

• Pairs of corresponding angles are not congruent.

• Pairs of corresponding angles are congruent.

• Pairs of corresponding angles are supplementary.

• Pairs of corresponding angles are parallel.

What is the consecutive interior angles theorem?

• Pairs of interior angles on the same side of the transversal are parallel.

• Pairs of interior angles on the same side of the transversal are complementary.

• Pairs of interior angles on the same side of the transversal are congruent.

• Pairs of interior angles on the same side of the transversal are supplementary.

What is the consecutive exterior angles theorem?

• The consecutive exterior angles theorem states that if a transversal intersects two parallel lines, then the alternate interior angles are congruent.

• The consecutive exterior angles theorem states that if a transversal intersects two parallel lines, then the consecutive interior angles are supplementary.

• The consecutive exterior angles theorem states that if a transversal intersects two parallel lines, then the consecutive exterior angles are supplementary.

• The consecutive exterior angles theorem states that if a transversal intersects two parallel lines, then the consecutive exterior angles are congruent.

If two lines are cut by a transversal and the alternate interior angles are congruent, what can you conclude about the lines?

• The lines are perpendicular.

• The lines are parallel.

• The lines are intersecting.

• The lines are skew.
