Scale & Proportion | Easy Trick for Similar Figures, Maps & Models

In this video, we’ll go over one of the most useful Algebra 1 skills: proportions and scale drawings. You’ll see how to use a simple math trick with proportions to solve problems about similar triangles, maps, and models—including the Parthenon! If you’ve ever wondered how to find missing side lengths in similar figures, measure distances on a map, or figure out how big a model should be, this video will walk you through it step by step with clear examples. 📌 You’ll learn how to: Write and solve proportions for similar triangles Use proportions for scale drawings and models Apply proportions to real-world maps Cross multiply and solve quickly with this math hack How to find lengths in scale models and scale drawings (including maps). Set up your initial ratio using two corresponding lengths. Then finish writing the other side of the proportion using the same corresponding relationship. Last, cross multiply and solve. This video could work for #Algebra students who were absent, or in a flipped classroom.
