This example demonstrates the sections of rectangular prisms. It involves the concept of sections in solid geometry, and uses GeoGebra commands such as Polygon, PointIn, Translate, Rotate, etc., to dynamically show different sections of the rectangular prism. Suitable for middle school and above students or teachers.
