4.G.1:
Geometry
Draw And Identify Lines And Angles, And Classify Shapes By Properties Of Their Lines And Angles.
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
4.G.2:
Geometry
Draw And Identify Lines And Angles, And Classify Shapes By Properties Of Their Lines And Angles.
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.
5.G.3:
Geometry
Classify Two-Dimensional Figures Into Categories Based On Their Properties.
Understand that attributes belonging to a category of two- dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
