This example demonstrates the geometric process of slicing a cube with a plane parallel to its base. It involves core concepts in solid geometry, cross-sectional shapes, and spatial visualization. Construction highlights include commands like Sequence, Element, Point, Polygon, and Segment in GeoGebra. Suitable for high school geometry education or spatial reasoning development.
