This example demonstrates different sections of a cube. It involves the concept of sections in solid geometry, using GeoGebra commands such as Cube, Polygon, PointIn, Translate, Rotate, etc., to dynamically show the shapes of the cube's sections when cut by different planes. Suitable for middle school and above students or teachers for teaching and learning.
