Exploring Transversals and Parallel Lines

What is the definition of parallel lines?

• Lines that intersect at right angles

• Lines that never touch each other

• Lines that cross at least two other lines

• Lines that form a right angle with a transversal

What are interior angles?

• Angles formed by a single line

• Angles formed inside the parallel lines

• Angles that are always equal

• Angles formed outside the parallel lines

Which of the following is an example of alternate interior angles?
