A line of symmetry divides a figure into to halves that are the mirror images of each other. Fold a square sheet of paper exactly in half. When you unfold the paper you will see the crease down the center. That is an example of a line of sy...

Illustrated Math Dictionary - Definition of Line Symmetry ... Another name for reflection symmetry. One half is the reflection of the other half. The "Line of Symmetry" (shown here in white) is the imaginary line where you could fold the image and have both halves match exactly.

If you can reflect (or flip) a figure over a line and the figure appears unchanged, then the figure has reflection symmetry or line symmetry. The line that you reflect over is called the line of symmetry. A line of symmetry divides a figure into two mirror-image halves.

Line Symmetry is also know as Bilateral Symmetry ... The most common type of symmetry is line or bilateral symmetry. A figure that can be folded in such a way that one-half of it lies exactly on the other half is said to have line symmetry. The two parts of the original pictures are mirror images of each other and are said...
