Grade 4 Math — 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.A regular shape has 8 lines of symmetry. How many sides does it have?

  2. 2.How many lines of symmetry does a regular pentagon have?

  3. 3.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

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

  6. 6.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
    • 0
    • 2
    • 3
    • 5
    • 1

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

    Groups: Has a line of symmetry · Has none

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

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

Answer key — Grade 4 Math — Line symmetry

  1. 1. 8
  2. 2. 5
  3. 3. 3 — the upright line
  4. 4. 0
