Geometry: Transformations and Pythagorean Theorem · Geometry

Dilations and Similarity

Using dilations to explore similarity and understanding the relationship between scale factors and area.

Key Questions

  1. 1How does a dilation differ from a rigid transformation?
  2. 2Why are all circles similar to each other, but not all rectangles?
  3. 3How can we use similarity to measure heights of objects that are too tall to reach?
