Area of Parallelogram and Triangles Workbench

This example demonstrates the calculation methods for the areas of parallelograms and triangles. By adjusting the sliders in the figure, you can observe the changes in area intuitively. The core mathematical concepts include the area formula of triangles and its applications. This example uses GeoGebra objects such as points, line segments, and polygons for construction. Suitable for middle school and above students to learn geometry and area calculation.
