Year 6 Maths — Line symmetry

Find the lines of symmetry of shapes and letters, and tell a mirror line from a line that only looks like one.

Name: ________________________

  1. 1.Sort each capital letter by whether it has a line of symmetry.

    Groups: Has a line of symmetry · Has none

    • R
    • T
    • M
    • F
    • A
    • P

  2. 2.How many lines of symmetry does the capital letter H have?

  3. 3.How many lines of symmetry does the capital letter F have?

  4. 4.Match each of these to the number of lines of symmetry it has.

    • The letter F
    • The letter T
    • The letter H
    • Equilateral triangle
    • Regular pentagon
    • 1
    • 0
    • 2
    • 3
    • 5

  5. 5.Put these in order by how many lines of symmetry they have, fewest first.

    • Equilateral triangle
    • The letter T
    • Square
    • Rectangle that is not a square
    • Scalene triangle
    • Regular hexagon

  6. 6.Which of these capital letters has no line of symmetry?

    • a) M
    • b) R
    • c) X
    • d) E

  7. 7.How many lines of symmetry does the capital letter T have?

  8. 8.Which of these shapes has exactly one line of symmetry?

    • a) Scalene triangle
    • b) Square
    • c) Rectangle that is not a square
    • d) Isosceles triangle
