Exploring Adding and Subtracting Rational Expressions

What defines parallel lines?

• Lines that intersect at a 90-degree angle

• Lines that never meet, regardless of length

• Lines that intersect at one point

• Lines that are perpendicular to each other

What is a transversal?

• A line that divides an angle into two equal parts

• A line intersecting two lines at different points

• A line that intersects two parallel lines at a 90-degree angle

• A line parallel to one of two lines it intersects

What are corresponding angles?

• Angles on opposite sides of the transversal

• Angles that sum up to 180 degrees

• Angles that are adjacent to each other

• Angles in the same position on each line intersected by the transversal

Are alternate interior angles congruent or supplementary?

• Both

• Neither

• Supplementary

• Congruent

What is true about alternate exterior angles?

• They are supplementary

• They are congruent

• They are on the inside of parallel lines

• They add up to 90 degrees

What defines consecutive interior angles?

• Angles that are congruent

• Angles that are outside the parallel lines

• Angles on the same side of the transversal and inside the parallel lines

• Angles that are on opposite sides of the transversal

What is the relationship between consecutive interior angles?

• They are complementary

• They have no specific relationship

• They are supplementary

• They are congruent

How do you find the measure of angles when given one angle in a parallel line and transversal setup?

• Using corresponding angles

• Using supplementary angles

• Using both corresponding and alternate angle properties

• Guessing based on the given angle

If one angle in a parallel line and transversal setup is 68 degrees, what is the measure of its corresponding angle?

• 180 degrees

• 112 degrees

• 68 degrees

• 90 degrees

What humorous note does the teacher end with regarding parallel lines?

• Parallel lines have a lot in common but never meet

• Parallel lines are always on the same page

• Parallel lines eventually cross paths

• Parallel lines are like trains on the same track
