Every answer with the reasoning behind it. Worth reading after you have tried the set — or on its own, if you are a parent marking it.

  1. Railway tracks stay the same distance apart and never meet. What kind of lines are they?

    Answer: Parallel

    Lines that never meet and stay the same distance apart are parallel.

  2. The corner of a book cover has two edges meeting at a right angle. What are those edges?

    Answer: Perpendicular

    Two lines meeting at a right angle are perpendicular.

  3. How many pairs of parallel sides does a square have?

    Answer: 2

    The top and bottom are one parallel pair; the left and right are another: 2 pairs.

  4. Which capital letter is made from two parallel lines and one line crossing them?

    Answer: H

    A capital H has two parallel uprights joined by a crossbar.

  5. Which of these pairs is parallel?

    Answer: The two long rails of a ladder

    The two long rails of a ladder run alongside each other and never meet, so they are parallel.

  6. How many pairs of perpendicular sides does a rectangle have?

    Answer: 4

    There is a right angle at each of the 4 corners, so 4 pairs of sides are perpendicular.

  7. Which statement about parallel lines is TRUE?

    Answer: They stay the same distance apart

    Parallel lines keep exactly the same gap between them all the way along.

  8. Which capital letter has two perpendicular lines?

    Answer: T

    The crossbar of a capital T meets its upright at a right angle.

  9. A window frame has an upright bar and a bar across it, meeting at a right angle. What are those two bars?

    Answer: Perpendicular

    Bars meeting at a right angle are perpendicular to each other.

  10. Which shape has NO parallel sides?

    Answer: Triangle

    Every pair of sides in a triangle meets at a corner, so none of them are parallel.
