Dilation Example by Eric Olivas
Loading the math board and drawing, please wait…
This example demonstrates the effect of a geometric transformation, specifically dilation (scaling), on a polygon. It involves core concepts like similarity transformation, scale factor, polygon construction, and intersection calculations. GeoGebra commands used include Polygon, Intersect, Dilate, and Line. Suitable for high school students learning geometric transformations and coordinate geometry.
