In collections Evaluating Statements about Dilations
This example demonstrates how to dilate a circle about its center, visually showing the effects of scaling on the circle. Key math concepts include geometric transformations, similar figures, and proportional relationships. It utilizes commands/objects like Circle, Circumference, PointIn, and Area from GeoGebra as outlined in the construction summary. Suitable for high school students learning about geometric transformations, similarity, and dynamic geometry exploration with GeoGebra.

GeoGebra Commands & Parameters

  1. Circle(zAxis, A) → c
  2. Circumference(c) → circumferencec
  3. PointIn(c) → Pointc_1
  4. Area(c) → a
  5. PointIn(c) → Pointc
