Area of Triangles in a Rectangle

This example demonstrates how to construct triangles within a rectangle and calculate their areas. Key math concepts include triangle area formulas, rectangle properties, Pythagorean theorem, and coordinate geometry. Construction highlights the use of GeoGebra commands/objects like Segment, OrthogonalLine, Point, Intersect, Polygon, Distance, and PointIn. Suitable for middle school and above students learning geometric constructions and area calculations.
