This stage focuses on properties of figures in three-dimensional space. The content is typically divided as follows:
The for Grades 10–11 (and Grades 7–9) is a comprehensive curriculum that covers both Planimetry (plane geometry) and Stereometry (solid geometry). It is structured for both basic and advanced (profile) levels. Grades 10–11: Stereometry (Solid Geometry) smirnova geometriia uchebnik - klass gdz
