Recognize and draw lines of symmetry and line-symmetric figures (4.G.A.3)

Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.


  • Identify line symmetry in regular polygons

    In this lesson you will learn how to identify line symmetry in regular polygons by folding the figure into matching, or symmetrical parts.
