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. How many lines of symmetry does a square have?

    Answer: 4

    Two lines through the middle of opposite sides and two along the diagonals: 4 in all.

  2. How many lines of symmetry does a rectangle that is not a square have?

    Answer: 2

    One line across the middle and one down the middle: 2 lines of symmetry.

  3. Which capital letter has a vertical line of symmetry?

    Answer: A

    A capital A folds onto itself along a vertical line down its middle.

  4. Which capital letter has a horizontal line of symmetry?

    Answer: E

    A capital E folds onto itself along a horizontal line through its middle bar.

  5. How many lines of symmetry does an equilateral triangle have?

    Answer: 3

    A line from each corner to the middle of the opposite side gives 3 lines of symmetry.

  6. Which of these shapes has no line of symmetry?

    Answer: Scalene triangle

    A scalene triangle has three different side lengths, so it cannot be folded onto itself.

  7. Which of these shapes will NOT tessellate on its own, leaving no gaps?

    Answer: Circle

    Circles always leave curved gaps between them, so they cannot tessellate.

  8. How many lines of symmetry does a regular hexagon have?

    Answer: 6

    A regular hexagon has 6 lines of symmetry: 3 through opposite corners and 3 through opposite sides.

  9. Which capital letter has both a vertical and a horizontal line of symmetry?

    Answer: H

    A capital H folds onto itself both across and down.

  10. Why do regular hexagons tessellate?

    Answer: Three of their 120° angles meet to make 360°

    Each angle of a regular hexagon is 120°, and three of them meet at a point to make a full 360° with no gap.
