What is a line of symmetry? A line on which a figure can be folded so that both sides match. Maryland Content Standard 2.E.2 Identify and describe symmetry in geometric figures or pictures. (Up to four lines of symmetry)

To be a line of symmetry, the shape must have two halves that match exactly. When you trace a heart onto a piece of folded paper,

and then cut it out, the two half hearts make a whole heart. The two halves are symmetrical. Which of these flags have a line of symmetry?

United States of America Maryland Canada England

What about these math symbols? Do they have symmetry? How many lines of symmetry to these regular polygons have?

Do you see a pattern? You can look to see if your name has symmetrical letters in it too!
