Unit 3, Lesson 12# Modeling Using Similarity

EngageNY 45 min(s)

Students use properties of similar triangles to solve real-world problems. This lesson is the first opportunity for students to see how the mathematics they have learned in this module relates to real-world problems. Each example, exercise, and item in the Problem Set is in a real-world context (e.g., the height of a tree, the distance across a lake, and the length needed for a skateboard ramp). Many of the problems begin by asking students if they have enough information to determine if the situation described lends itself to the use of similar triangles.
