What will I learn?
The Similar Triangles Course gives you a focused toolkit for modeling real-world length problems with clear diagrams, auxiliary lines, and accurate proportions. You will practice right- and non-right-triangle setups, refine algebraic solving, and avoid common correspondence errors. The course also builds concise explanation, presentation, and citation skills through a short, polished mini-project based on authentic applications.
