Partitioning a Line Segment: Dynamic Ratio Point Construction

① This example demonstrates how to partition a line segment at a given ratio, showing the point P moving along the segment as the ratio changes. ② Core math concepts include section formula, ratio, similar triangles, and coordinate geometry. ③ Construction uses GeoGebra commands such as Segment to draw AB, and Textfield/InputBox objects (A, B, C, D, E, P) to input parameters, with dynamic updates of point P based on the ratio. ④ Suitable for middle and high school students and teachers exploring plane geometry, proportions, and coordinate systems, as well as for investigating the connection between segment division and similar triangles.
