Previous Standard Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
Next Standard 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.
Geometry Draw and identify lines and angles, and classify shapes by properties of their lines and angles. 1Draw points, lines, line segments, rays, angles (right, acute, obtuse], and perpendicular and parallel lines. Identify these in two-dimensional figures.
