Dilation Transformation Demo by M. Herring

This example demonstrates polygonal dilation in a plane, showing how shapes change size via a center point and scale factor. Core math concepts include transformation, similarity, coordinate geometry, and vectors. Construction uses Polygon command for shapes, with points A, B, C as vertices, t1 as scale factor, c as center, and a, b for auxiliary purposes. Suitable for high school mathematics teaching on transformation properties and applications.
