Lines of Symmetry
Grade 2 · Math · Geometry · Georgia, USA
Lesson Summary
A line of symmetry divides a shape into two halves that are mirror images of each other.
Explanation
If you can fold a shape in half and both sides match perfectly, the fold line is called a line of symmetry. A heart has one line of symmetry right down the middle. A square has four lines of symmetry. Some shapes, like a circle, have many lines of symmetry. Not all shapes have a line of symmetry. Try folding paper shapes to see if both halves match up!
