(9) Congruence and the geometry of size. The student analyzes properties and describes relationships in geometric figures. The student is expected to:

• (A) formulate and test conjectures about the properties of parallel and perpendicular lines based on explorations and concrete models;

• (B) formulate and test conjectures about the properties and attributes of polygons and their component parts based on explorations and concrete models;

• (C) formulate and test conjectures about the properties and attributes of circles and the lines that intersect them based on explorations and concrete models; and

• (D) analyze the characteristics of polyhedra and other three-dimensional figures and their component parts based on explorations and concrete models.
