Exploring Parallel Lines and Angles

What is the defining characteristic of parallel lines?

• They eventually meet at some point.

• They intersect at a 90-degree angle.

• They form a triangle.

• They never intersect and are always equidistant.

If angle 1 measures 110 degrees, what is the measure of angle 3?

• 90 degrees

• 180 degrees

• 110 degrees

• 70 degrees

Which statement is true about corresponding angles?
