Similarity Transformation: Line Segment Dilation

This example demonstrates the dilation of a line segment under a similarity transformation. Key math concepts include similar triangles, central symmetry, and proportional relationships. Construction highlights involve using GeoGebra commands like Point, Segment, Intersect, and Dilate to construct the scaled image of a line segment given a center point and scale factor, suitable for middle school and above learning geometric transformations and similar figures.
