This example demonstrates the concept of mean. Key mathematical concepts include the calculation method of mean. Using GeoGebra commands such as Point, OrthogonalLine, Intersect, etc., the geometric representation of mean is constructed. Suitable for middle school mathematics education to help students understand the geometric meaning of mean.

AI Drawing Prompt Reference

Draw a point and construct five perpendicular lines from it. Take points on these lines, connect them with segments, and find their intersections. Finally, connect the intersection points to form a geometric shape that illustrates the concept of mean.
