About this worksheet

What students practice

  • Students decide whether a dashed line is a line of symmetry by imagining a fold.
  • Students count the lines of symmetry in two-dimensional figures, including figures with none.
  • Students draw all the lines of symmetry on a square and a rectangle.

How to use

Review that a line of symmetry folds a figure into two halves that match exactly. Give students paper cutouts of a rectangle and a square to fold before they start Part 1.

Quilt Block Symmetry

Check fold lines, count lines of symmetry, and draw them on quilt patches.

Fold-line check

Grandma June's quilt club cuts patches in many shapes. A line of symmetry folds a patch into two halves that match exactly.

1.
Each patch has a dashed line drawn through it. Is the dashed line a line of symmetry? Sort the patches.
Line of symmetryNot a line of symmetry
2.
Circle every patch that has at least one line of symmetry.

3.
Leo says the dashed line on this rectangle patch is a line of symmetry because it cuts the patch into two triangles that are the same size. Is Leo right?
  • A. Yes, because the two triangles are the same size.
  • B. No, because a rectangle has no lines of symmetry.
  • C. No, because if you fold on the dashed line, the two halves do not land on top of each other.
  • D. Yes, because every line through the middle of a shape is a line of symmetry.
