The student must be able to identify two-dimensional figures, including circles, triangles, rectangles, rhombuses, and hexagons. The students must be able to see that a square is a special rectangle. Students must also be able to explain and justify their mathematical ideas and arguments using formal geometric language.

1.6 Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:
(D) identify two-dimensional shapes, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons and describe their attributes using formal geometric language
