STRAND 3: GEOMETRY AND TRIGONOMETRY (G)
In Grades K–5, students study figures such as triangles, rectangles, circles, rectangular solids, cylinders, and spheres. They examine similarities and
differences between geometric shapes. They learn to quantify geometric figures by measuring and calculating lengths , angles, areas and volumes. In
Grades 6-8, students broaden their understanding of area and volume and develop the basic concepts of congruence, similarity, symmetry and the
Pythagorean Theorem. They apply these ideas to solve geometric problems, including ones related to the real world.

In Grades 9–12, students see geometry developed as a coherent, structured subject. They use the geometric skills and ideas introduced earlier, such as
congruence and similarity, to solve a wide variety of problems. There is an emphasis on the importance of clear language (e.g. for postulates, definitions and
theorems) and on learning to construct geometric proofs. In this process, students build geometric intuition and facility at deductive reasoning. They use
elements of logic and reasoning as described in the Quantitative Literacy and Logic strand, including both direct and indirect proof presented in narrative
form. They begin to use new techniques, including transformations and trigonometry. They apply these ideas to solve complex problems about two- and
three-dimensional figures, again including ones related to the real world. Their spatial visualization skills will be developed through the study of the
relationships between two- and three-dimensional shapes.
STANDARD G1: FIGURES AND THEIR

Students represent basic geometric
figures, polygons, and conic sections and apply their
definitions and properties in solving problems and
justifying arguments, including constructions and
representations in the coordinate plane. Students
represent three-dimensional figures, understand the
concepts of volume and surface area, and use them
to solve problems. They know and apply properties
of common three-dimensional figures.
