Examples, videos, solutions, and worksheets to help Geometry and Grade 9 students learn about line symmetry or reflectional symmetry.
Symmetry in a figure exists if there is a reflection, rotation, or translation that can be performed and the image is identical. Reflectional symmetry exists when the figure can be folded over onto itself along a line. This line is called the "line of symmetry". In regular polygons, the number of lines of symmetry equals the number of sides in the polygon.
