Symmetry GCSE Questions

This video tutorial guides students through symmetry questions commonly found in GCSE exams. It covers identifying lines of symmetry in patterns, exploring rotational symmetry by rotating patterns, and altering symmetry by adding dots. The tutorial also includes a final question on determining symmetry order and lines of symmetry. The video concludes with encouraging words for exam preparation.

Which pattern has only one line of symmetry?

• Pattern B

• Pattern A

• Pattern C

• None of the above

What is the order of rotational symmetry for a pattern that matches the original twice during a full 360° rotation?

• 4

• 1

• 2

• 3

How can you reduce the order of rotational symmetry from 4 to 2?

• Add a line of symmetry

• Rotate the shape 180°

• Remove a line of symmetry

• Place two dots on the shape

What must be true about a shape with an order of rotational symmetry of three and no lines of symmetry?

• It matches the original once in a 360° rotation

• It has no rotational symmetry

• It matches the original three times in a 360° rotation

• It has three lines of symmetry

Which shape can be ruled out if it has lines of symmetry but needs to have an order of rotational symmetry of three?

• A shape with multiple lines of symmetry

• A shape with an order of rotational symmetry of two

• A shape with one line of symmetry

• A shape with no lines of symmetry
