Understanding Parallel Lines and Transversals: Identifying Angles and Patterns

What is the definition of parallel lines?

• Lines that intersect at right angles

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

• Lines that intersect at any angle

• Lines that are perpendicular to each other

Which of the following is true about vertical angles?

• They are always supplementary

• They are always congruent

• They are always complementary

• They are always adjacent

What is the sum of the measures of supplementary angles?

• 90 degrees

• 270 degrees

• 180 degrees

• 360 degrees

What are corresponding angles?

• Angles that are adjacent to each other

• Angles that are opposite each other

• Angles that are on alternate sides of the transversal

• Angles that are on the same side of the transversal and in matching positions

Which angles are formed on the inside of parallel lines and a transversal?

• Exterior angles

• Interior angles

• Vertical angles

• Supplementary angles

What is true about alternate interior angles?

• They are always congruent

• They are always supplementary

• They are always complementary

• They are always adjacent

Which of the following describes alternate exterior angles?

• They are adjacent to each other

• They are on the inside of the parallel lines

• They are on alternate sides of the transversal and outside the parallel lines

• They are on the same side of the transversal

If angle 1 is 121 degrees and angle 2 is supplementary to angle 1, what is the measure of angle 2?

• 59 degrees

• 121 degrees

• 180 degrees

• 90 degrees

Which angle is congruent to angle 3 if angle 3 is an alternate interior angle?

• Angle 5

• Angle 1

• Angle 2

• Angle 4

What pattern is observed in the arrangement of angles formed by a transversal intersecting parallel lines?

• A linear pattern

• A random pattern

• A circular pattern

• A zigzag pattern
