- Lines of Symmetry
If you fold a shape in half, where the two halves match then the image is said to have line symmetry or mirror symmetry. This folded line is a line of reflection.
Term: Symmetry: Exact similar part facing each other.
Observe the following pictures carefully and determine the lines of symmetry.
- Get a plain sheet of paper. Draw a straight line down the middle. Draw a shape on the left of the line and then place a mirror on the line. Observe the reflection of the image.
- Build symmetrical designs with pattern blocks or on a geoboard.
