: Transitions into stereometry (3D geometry) and complex calculations involving volume and spatial figures.
: Includes more advanced problem-solving intended to prepare students for final exams. : Transitions into stereometry (3D geometry) and complex
: The GDZ is intended as a tool for self-checking rather than just copying. It helps students identify specific gaps in their logic before formal classroom testing. the Theorem of Thales
: Focuses on basic constructions, the Theorem of Thales, and properties of triangles and parallel lines. : Transitions into stereometry (3D geometry) and complex
