Bilateral Symmetry

This occurs when a figure can only be divided into equal halves on one line. Such a figure has one line of symmetry.Line Symmetry

A figure has line symmetry or reflection symmetry when it can be divided into equal halves that match.Lines of Symmetry

Lines of symmetry are the lines that can be drawn to divide a figure into equal halves.Reflection

A reflection is a transformation that flips a figure on the coordinate plane across a given line without changing the shape or size of the figure.Rotational Symmetry

A figure has rotational symmetry if it can be rotated less than around its center point and look exactly the same as it did before the rotation.### Image Attributions
