Flat figures are objects. A figure is considered flat if all its points lie on a single plane. Key Measurements : They have only length and width .
Understanding the transition from flat (plane) shapes to volumetric (solid) bodies is a foundational step in 4th-grade geometry. It bridges the gap between simple drawing and understanding the physical world in three dimensions. ploskie i obieemnye figury 4 klass prezentatsiia

: They have three dimensions— length, width, and height (or depth).
Volumetric figures are objects that occupy space.
: They consist of faces (flat surfaces), edges (where two faces meet), and vertices (points where edges meet). Examples :
