Symmetry
Grade 1 · Math · Geometry · Alberta, Canada
Lesson Summary
Find out if both sides of a shape match when you fold it in half.
Explanation
A shape has symmetry when you can fold it in half and both sides match exactly. The fold line is called a line of symmetry. A heart, a butterfly, and the letter A all have symmetry. If you fold a heart down the middle, the left side looks just like the right side. Not all shapes are symmetrical — some shapes do not match when folded.
