Addition and Subtraction
This example demonstrates the geometric properties of a rectangle interactively, allowing users to adjust vertices dynamically to observe changes. Core math concepts include polygons, coordinate geometry, linear functions, and geometric construction. GeoGebra commands used are Intersect, OrthogonalLine, Polygon, Perimeter, and PointIn. Suitable for high school mathematics education to understand plane geometric figures and their attributes and calculations.
