Answers and explanations for all 10 questions

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. Which statement about parallel lines is TRUE?

    Answer: They never meet and stay the same distance apart

    Parallel lines run in the same direction, never meet, and stay the same distance apart.

  2. How many pairs of parallel sides does a regular hexagon have?

    Answer: 3

    A regular hexagon has 3 pairs of opposite sides, and each pair is parallel.

  3. Line J is perpendicular to line K, and line K is perpendicular to line L. How do line J and line L relate?

    Answer: Parallel

    J and L both meet K at 90°, so they run the same way as each other: they are parallel.

  4. At which of these times are the hour and minute hands of a clock perpendicular?

    Answer: 3.00

    At 3.00 the minute hand points at 12 and the hour hand at 3, which is a right angle.

  5. Which capital letter is made of two pairs of parallel lines?

    Answer: H

    A capital H has two uprights that are parallel, and the crossbar is perpendicular to both.

  6. A transversal crosses two parallel lines. One of the corresponding angles is 65°. What is the other corresponding angle?

    Answer: 65°

    Corresponding angles on a transversal across parallel lines are equal, so the other is 65°.

  7. A square has sides AB, BC, CD and DA. Which pair is perpendicular?

    Answer: AB and BC

    AB and BC meet at B, a corner of the square, so they are perpendicular.

  8. A transversal crosses two parallel lines. One of the co-interior angles is 110°. What is the other?

    Answer: 70°

    Co-interior angles on a transversal across parallel lines add to 180°, so 180 − 110 = 70°.

  9. Which pair of lines is parallel?

    Answer: The opposite edges of a book cover

    The opposite edges of a book stay the same distance apart and never meet.

  10. A rhombus that is not a square has two pairs of parallel sides. How many of its angles are right angles?

    Answer: 0

    A rhombus has right angles only when it is a square, so this one has 0.
