Draw and identify lines and angles, and classify shapes by properties of their lines and angles
4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional 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
matching parts. Identify line symmetric figures and draw lines of
