Symmetry

Hard⏱ 23 min
A butterfly's wings match perfectly on both sides — that's symmetry!

A has when one is a of the other. The is called the of (or ).

✨

A has 4 of — you can it in in and both .

When you fold a square in half, both sides match exactly along the fold.
A square's 4 lines of symmetry: across, down, and both diagonals. Fold along any one and the halves match.
An equilateral triangle has 3 lines of symmetry — one from each corner to the middle of the opposite side.

To for , the the . If both up , the is a of . A has 2 of , while a has 6.

🗂️ Sort each shape by how many lines of symmetry it has.

  • Isosceles triangle

  • Square (4 lines)

  • Rectangle (2 lines)

  • Irregular quadrilateral

is all around you in : , , and are . like A, M, and T have one of .

A snowflake has six matching sides — nature makes perfect symmetry!
A butterfly has one vertical line of symmetry — its left and right wings are mirror images.

A (where all are the ) has the of of as it has . A has 3, a has 4, a has 5, and a has 6. That is a very !

A regular hexagon has 6 sides — and exactly 6 lines of symmetry. The pattern always matches!

🔗 Match each regular shape to its number of lines of symmetry.

  • Equilateral triangle

  • Square

  • Regular pentagon

  • Regular hexagon

To the of a on , how many each is from the , then the the on the other . A 2 to the of the to a 2 to the .

A has many of — you can the in any and both !

A leaf's two halves mirror each other perfectly along its middle stem.

🧩 Order these shapes from fewest to most lines of symmetry.

  1. Regular hexagon (6 lines)
  2. Square (4 lines)
  3. Rectangle (2 lines)
  4. Scalene triangle (0 lines)

Some are and some are not. A, H, I, M, O, T, U, V, W, X and Y have at one of . like F, G, J, L, P, Q and R have — you them so the .

The letter A has 1 line of symmetry — a vertical fold down the middle.
The letter H has 2 lines of symmetry — one vertical and one horizontal.
