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.
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.
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.
Which capital letter has a vertical line of symmetry?
Answer: A
A capital A folds onto itself along a vertical line down its middle.
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.
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.
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.
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.
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.
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.
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.
