1. 1. Which statement best describes parallel lines in the same plane?

   • A. Lines that cross at right angles
   • B. Lines that never meet and stay the same distance apart
   • C. Lines that meet at one point
   • D. Lines that are always drawn horizontally

2. 2. What does the statement PQ \parallel RS tell us about the line segments PQ and RS?

   • A. PQ is twice as long as RS
   • B. PQ and RS meet at point Q
   • C. PQ is parallel to RS
   • D. PQ crosses RS at right angles

3. 3. Wanjiru measures the perpendicular gap between segments JK and LM. At J the gap is 32 mm and at K the gap is also 32 mm. What is the difference, in millimetres, between the two gaps? (A difference of 0 shows the segments are parallel.)

   Type your answer (in mm) in the lesson.

4. 4. What one word describes two lines that are the same distance apart at every point along them?

   Type your answer in the lesson.

5. 5. When using a ruler to test whether two lines are parallel, how should the ruler be placed across the gap?

   • A. At right angles (perpendicular) to the lines
   • B. Slanted at any angle that fits
   • C. Along the first line only
   • D. Touching only one line at its end
