Geometric Construction of the Flag of Monaco

This applet demonstrates the geometric construction of the flag of Monaco using GeoGebra's Polygon tool. The student works within a Cartesian coordinate system, defining specific vertex coordinates to build two horizontal rectangles of equal width—one colored red and the other white—arranged to accurately reproduce the bicolor design of the Monaco flag. The red band occupies the upper portion and the white band the lower portion, maintaining the official flag proportions. Through this interactive construction, learners practice fundamental polygon creation in coordinate geometry, reinforcing how mathematical coordinates can precisely define real-world shapes. The applet allows students to adjust vertex positions and observe how changes affect the resulting figure, deepening their understanding of the relationship between algebraic coordinates and geometric forms. It serves as an engaging introduction to basic geometric construction techniques and practical coordinate system applications, making it suitable for introductory geometry courses where students learn to combine visual and analytical reasoning.
