PolygonCalculusGeometric Construction
This example demonstrates the centroid of a square. Key mathematical concepts include the definition and calculation of the centroid in geometry. Using GeoGebra commands such as Point, Segment, Polygon, and Centroid, the process of calculating the centroid is visually illustrated. Suitable for students at the junior high school level and above to learn geometric construction and related concepts.

AI Drawing Prompt Reference

Draw a square ABCD, then find and mark its centroid G. Next, draw the diagonals AC and BD, and the midpoints of each side, forming a new quadrilateral HMLK. Finally, calculate and mark the areas of square ABCD and quadrilateral HMLK.
