Overview

Symmetrical designs appear when a shape or pattern looks the same after a fold or after a turn. Reflection symmetry uses a line of symmetry, while rotational symmetry appears when a figure looks the same after being turned through part of a full turn. Letters, windmills, numbers, and block prints al

Key Concepts

A figure has reflection symmetry when

A figure has reflection symmetry when one half matches the other half exactly after folding along a line of symmetry.

A line of symmetry is

A line of symmetry is a fold line that divides a figure into two matching parts.

Letter A has a vertical line

Letter A has a vertical line of symmetry. It can be made by folding paper in half, drawing half of the letter along the fold, cutting it out, and open

Letter H has two lines

Letter H has two lines of symmetry, one vertical and one horizontal. It can be made by folding the paper into one-fourth, drawing one-fourth of the le

A figure has rotational symmetry when

A figure has rotational symmetry when it looks the same after being turned through part of a full turn.
