This example visually demonstrates the concept of completing the square in simplifying quadratic function expressions. It involves core math concepts like quadratic functions, squares, and geometric transformations including rotation. Constructed using GeoGebra commands such as RandomElement, Circle, Polygon, Ray, Point, Segment, PointIn, Intersect, and Textfield, it provides an interactive way to understand the geometric meaning of completing the square. Suitable for high school mathematics education.
