Draw and identify lines and angles, and classify shapes by properties of their lines and angles
4.G1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
Geoboard Line Segments
Angles on the Geoboard
Angle Barrier Game
4.G2 Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
4.G3 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
Symmetry on the Geoboard
Symmetry in Regular Polygons
