Dilations and Similarity

Using scale factors and centers of dilation to create similar figures and understand proportional growth.

Key Questions

  1. 1What is the difference between congruence and similarity in geometric terms?
  2. 2How does a scale factor greater than one affect the area of a figure compared to its perimeter?
  3. 3How can we use similarity to measure heights or distances that are impossible to reach directly?
