Grade 5 Symmetry Quiz

What is reflection symmetry in a 2-D shape?

• A shape has no symmetry

• A shape has a line that divides it into two identical halves that look the same and are mirrored

• A shape can slide to match another shape

• A shape can rotate and still look the same

How is reflection symmetry different in a 3-D shape?

• A 3-D shape can reflect over a plane, not just a line

• A 3-D shape cannot have symmetry

• A 3-D shape has infinitely many symmetries

• A 3-D shape can only have rotational symmetry

A shape has rotational symmetry if…

• It can be flipped over a line and still match.

• It exactly overlaps itself one or more times within a 360° turn.

• It has a reflection symmetry with an odd number of sides.

• It is a regular polygon.

What does the order of rotational symmetry describe?

• The number of times a shape fits onto itself within a 360° turn

• The way a shape is divided into equal parts

• The number of lines of symmetry in a shape

• The number of sides a shape has

Brooke cut out the shape of a star, coloured in one of its corners, traced it on a piece of paper, spun it 360°, and counted how many times the cutout completely covered the traced star before the coloured in corner made it back to its original position. What is Brooke trying to find?

• Order of rotation

• Planes of symmetry

• Reflection symmetry

• Lines of symmetry

What is the order of rotational symmetry of a regular hexagon?

• 6

• 12

• 3

• 2

How many rotation and reflection symmetries does this shape have?

• Infinite rotation, infinite reflection

• Infinite rotation, 1 reflection

• 1 rotation, 1 reflection

• 0 rotation, 0 reflection

What is central symmetry?

• A shape that has no symmetry

• Reflection symmetry through a straight line

• Rotational symmetry by 90°

• Rotational symmetry by 180°

Which of the following Indigenous designs often display symmetry?
