Year 7 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.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
    • 3
    • 5
    • 0
    • 2
    • 1

  2. 2.This kite has one line of symmetry. Three lines have been drawn on it. Tap the one that is a line of symmetry.

    Write the number of the part.

    123

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

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

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

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

  6. 6.A regular shape has 8 lines of symmetry. How many sides does it have?

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

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

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