: Includes more advanced problem-solving intended to prepare students for final exams.

: The solutions cover tasks organized into three distinct difficulty levels (A, B, and C), allowing students to practice at a level that matches their current understanding.

: Transitions into stereometry (3D geometry) and complex calculations involving volume and spatial figures.

: 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.

: Focuses on basic constructions, the Theorem of Thales, and properties of triangles and parallel lines.

: The materials span key geometric concepts across grade levels:

The primary feature of the (specifically for grades 7–11) is its structure, which mirrors the textbook's multi-level differentiation . These solutions are designed to support a curriculum where tasks are categorized by difficulty to accommodate different learning speeds. Core Features of Ershova's Geometry GDZ

: Covers quadrilaterals, area calculations, triangle similarity, circles, and vectors.
