Symmetry

Symmetry is when something matches on both sides. If you draw a line down the middle of a butterfly, both sides look the same. That line is called a line of symmetry. Many things in nature and art have symmetry. It makes shapes look balanced and pretty.

Types of Symmetry

There are different kinds of symmetry. Line symmetry means you can fold a shape in half and both sides match. A square has four lines of symmetry. Rotational symmetry means a shape looks the same when you spin it. A starfish has rotational symmetry because it looks the same as you turn it.

Symmetry Around Us

Symmetry is everywhere. Our faces are almost symmetrical. Snowflakes have six-sided symmetry. Many buildings, flags, and logos use symmetry because it looks nice. Artists often use symmetry to make beautiful patterns and designs.
