Exploring Parallel Lines and Transversal Concepts

What is the definition of parallel lines?

• Lines that curve and meet at multiple points.

• Lines that form right angles.

• Lines that never intersect and are always the same distance apart.

• Lines that intersect at one point.

How many individual angles are formed when a transversal intersects two parallel lines?

• Six

• Four

• Eight

• Ten

What is the sum of the angles formed by a linear pair?

• 90 degrees

• 360 degrees

• 120 degrees

• 180 degrees

Which of the following pairs of angles are always congruent?

• Corresponding angles

• Complementary angles

• Adjacent angles

• Supplementary angles

What are vertical angles?

• Angles that are adjacent and add up to 180 degrees.

• Angles that are on the inside of the parallel lines.

• Angles that are opposite each other when two lines intersect.

• Angles that are on the same side of the transversal.

Which angles are on the inside of the parallel lines but on opposite sides of the transversal?

• Alternate exterior angles

• Alternate interior angles

• Corresponding angles

• Same side interior angles

What is the relationship between same side interior angles?

• They are complementary.

• They are congruent.

• They are supplementary.

• They are equal to 90 degrees.

If angle 2 is 55 degrees, what is the measure of angle 7?

• 55 degrees

• 125 degrees

• 75 degrees

• 105 degrees

Which angles are formed by intersecting lines and are always congruent?

• Same side exterior angles

• Alternate interior angles

• Vertical angles

• Linear pair angles

What is the measure of angle 4 if angle 5 is 102 degrees?

• 102 degrees

• 78 degrees

• 60 degrees

• 120 degrees
