Exploring Parallel Lines and Transversal Concepts

What is the defining characteristic of parallel lines?

• They never intersect and are coplanar.

• They form a right angle with a transversal.

• They are always perpendicular.

• They intersect at one point.

How are parallel lines marked in a diagram?

• With a single arrow on each line.

• With two arrows on each line.

• With a circle on each line.

• With a single or double arrow depending on the pair.

What is true about corresponding angles formed by parallel lines and a transversal?

• They are congruent.

• They are always supplementary.

• They are always acute angles.

• They are always right angles.

What is the relationship between alternate interior angles when the lines are parallel?

• They are equal to 90 degrees.

• They are complementary.

• They are congruent.

• They are supplementary.

What do we call angles that add up to 180 degrees?

• Supplementary angles

• Congruent angles

• Vertical angles

• Complementary angles
