Class Experience

This module covers dilations, defining similarity as rigid transformations combined with dilation, and using proportional relationships in similar figures. It also develops right-triangle trigonometry by defining ratios from similar acute-angle right triangles and applying those ratios to solve geometric and applied problems.

Learning Outcomes

  • Describe and practice dilations and similarity transformations.

  • Define similarity as rigid transformations plus dilation.

  • Find and apply proportional relationships in similar figures.

  • Use similar triangles to derive and apply the Pythagorean relationship.

  • Define trigonometric ratios from similar right triangles and apply them to solve problems.
