Geometric Transformations and Logic · Geometry

Dilations and Similarity

Exploring how scaling factors change the size of a figure while maintaining its proportional shape.

Key Questions

  1. 1How does changing the center of dilation affect the final position of the image?
  2. 2What is the relationship between the scale factor and the ratio of the areas?
  3. 3How do we distinguish between congruence and similarity in geometric figures?
