Standard 4.G.3 – Lines of symmetry

Standard 4.G.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.

Explanation: We are learning about symmetrical figures. Watch the videos below to help get an understanding. If you can draw a line down the middle and fold it over to match perfectly, it is symmetrical.
