IX. Communication and Representation Geometry and measurement. The student applies mathematical process standards to classify figures by attributes and properties. The student is expected to Classify two-dimensional figures in a hierarchy of sets and subsets using graphic organizers based on their attributes and properties. Readiness Standard Classify two-dimensional figures in a hierarchy of sets and subsets using graphic organizers based on their attributes and properties. Readiness Standard Classify TWO-DIMENSIONAL FIGURES IN A HIERARCHY OF SETS AND SUBSETS USING GRAPHIC ORGANIZERS BASED ON THEIR ATTRIBUTES AND PROPERTIES Including, but not limited to: Two-dimensional figure a figure with two basic units of measure, usually length and width – Classify applying an attribute to categorize a sorted group – Attributes of two-dimensional figures characteristics that define a geometric figure (e.g., sides, vertices, etc.) – Properties of two-dimensional figures relationship of attributes within a geometric figure (e.g., a square has 4 congruent sides and 4 right angles, – etc.) and between a group of geometric figures (e.g., a square and a rectangle both have 4 sides and 4 right angles; however, a square has 4 congruent sides but a rectangle has only opposite sides congruent; etc.) Regular figure a polygon with all side lengths and angles congruent – Irregular figure a polygon with side lengths and/or angles that are not all congruent – Attributes of two-dimensional figures Side a line segment that forms the boundary of a two-dimensional figure – Number of sides Length of sides Vertex (vertices) in a two-dimensional figure the point (corner) where two sides of a two-dimensional figure meet – Number of vertices Angle two rays with a common endpoint (the vertex) – Types of angles
