Each unit above has a link to a high school Geometry newsletter that contains additional information and resources. For newsletters for middle school Geometry, visit Geometry GT8.

The Year at a Glance provides an overview of the mathematics content taught in the course.

Instructional time should focus on

  • forming, analyzing, testing and applying geometric conjectures;
  • applying geometric transformations to build understanding of congruence, similarity, and symmetry;
  • developing deductive and inductive reasoning skills through proof; and
  • extending the study of two- and three- dimensional analysis of plane and space figures using postulates, theorems, and corollaries.
