Dilation Transformation Demo by Kate Rimando
Loading the math board and drawing, please wait…
This example demonstrates the process of similar transformation of a shape given a scale factor and a point of dilation, involving core math concepts like similarity transformation, scale factor, translation, and coordinate geometry. It uses GeoGebra commands Polygon, Dilate, Ray and objects A, B, C, D, poly1, P, ScaleFactor. Suitable for high school students learning geometric transformations and their properties and applications.
