Proportion Applications in Geometry
Relationship Goals
When two shapes are similar or in proportion to each other, their sides form equivalent ratios or relationships. Put simply, you can set us a proportion problem with corresponding sides of similar shapes.
STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES
Make sure to note the following:
Prerequisite: You may want to review solving proportion problems before starting this lesson.
Similar shapes are shapes that are scaled copies of each other. Imagine blowing up or shrinking down an image on a computer, you keep the proportions the same but change the size of the object. When two shapes are similar, their corresponding sides will be in proportion, meaning that you can set up an algebraic proportion problem to solve for a missing side length.
