Cluster: Classify two-dimensional figures into categories based on their properties

Standard: Classify two-dimensional figures into categories based on their properties. Classify two-dimensional figures in a hierarchy based on properties.

Degree of Alignment: Not Rated (0 users)

Cluster: Draw and identify lines and angles, and classify shapes by properties of their lines and angles

Standard: 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.
