In collections TWO PARTS OF A CUBE
This example demonstrates two parts of a cube. It involves core mathematical concepts such as cube, line segment, coordinates, and continuity. Using GeoGebra commands like Point, Cube, Midpoint, Line, Vector, Translate, Rotate, Polygon, Segment, etc., the two parts of the cube can be constructed. Suitable for high school geometry education.
