Module 6: Proportional Reasoning in Similar Triangles
Task Introduction
"Welcome to this module on proportional reasoning and similar triangles! In this module, you’ll explore how proportional relationships apply to geometry, specifically similar triangles, and connect these ideas to algebraic thinking. Let’s get started!"
Problem:
"The following triangles, ABC and DEF, are similar triangles, meaning their sides are proportional. Triangle ABC has side lengths AB = 8 and BC = 6, and triangle DEF has side length DE = 24. What is the length of EF in triangle DEF?"
Step-by-Step Prompts for Solving
1. Solving Using Cross-Products Strategy
Initial Prompt:
"Can you solve this problem by setting up a proportion and using the cross-products strategy? Write your proportion and solve for the unknown side, EF."
Hints for Teachers Who Are Stuck:
First Hint: "Start by setting up the proportion based on the corresponding sides: AB/DE = BC/EF. Substituting the known values gives (8/24) = (6/x). Can you solve for x using cross-multiplication?"
Second Hint: "Multiply both sides by 24 to eliminate the denominator. What do you get for x?"
If the Teacher Provides a Partially Correct Answer:
"You’ve set up the proportion correctly—great! How can you solve for x using cross-products or equivalent ratios?"
If the Teacher Provides an Incorrect Answer:
"It seems like there’s a small error in your setup. Remember, the corresponding sides are proportional: (8/24) = (6/x). Can you try again?"
If still incorrect: "The correct solution is x = 18 because (8/24) = (6/18), maintaining the proportional relationship."
If the Teacher Provides a Correct Answer:
"Excellent! Your cross-product calculation is correct, and EF = 18. How might you explain this strategy to your students?"
2. Solving Using Conceptual Reasoning
Initial Prompt:
"Now, let’s think conceptually about the relationship between the triangles. Notice that triangle DEF is an enlarged version of triangle ABC. What is the ratio between the corresponding sides, and how can you use it to find EF?"
Hints for Teachers Who Are Stuck:
First Hint: "Compare the corresponding sides AB and DE. If AB = 8 and DE = 24, what is the scale factor (ratio of enlargement) between the triangles?"
Second Hint: "Multiply BC (6) by the scale factor (3) to find EF. What do you get?"
If the Teacher Provides a Partially Correct Answer:
"You’ve identified the scale factor as 3—great! How can you apply this factor to BC to find EF?"
If the Teacher Provides an Incorrect Answer:
"It seems like the ratio isn’t being applied correctly. Remember, the sides of similar triangles are proportional. Multiply BC by the scale factor to find EF."
If still incorrect: "The correct solution is EF = 6 x 3 = 18."
If the Teacher Provides a Correct Answer:
"Well done! Using the scale factor, you found EF = 18. How might this conceptual approach help students understand proportional reasoning in geometry?"
Reflection and Discussion Prompts
Reflection on Strategy Use:
"You solved this problem using both the cross-products strategy and conceptual reasoning. Which method do you find more efficient for this problem, and why?"
Pedagogical Connection:
"Why is it important for students to explore both procedural and conceptual approaches to solving problems involving proportional relationships?"
Efficiency of Conceptual Reasoning:
"In this problem, conceptual reasoning was more direct than the cross-products strategy. How might you guide students to recognize when a conceptual approach is more efficient?"

Extension Activity: Generalizing the Problem
Task Introduction:
"Now, let’s extend this problem. Suppose the length of BC changes to 7, 8, 9, …, or n. What would the corresponding lengths of EF be? Can you write a general rule for EF in terms of BC?"
Prompts to Guide Teachers:
"What is the scale factor (ratio) between the triangles? How can you apply this ratio to find EF for each value of BC?"
"Write your results in a table. For example:
CopyEdit
BC       EF
7        ?
8        ?
9        ?
n        ?
"What pattern do you notice in the table? How can you generalize this relationship algebraically?"
Hints for Teachers Who Are Stuck:
First Hint: "Multiply each value of BC by the scale factor (3) to find EF. What do you get for BC = 7, 8, and 9?"
Second Hint: "To generalize, let BC = n. The length of EF is 3n because the ratio between the corresponding sides is constant."
If the Teacher Provides an Incorrect Answer:
"It seems like the scale factor wasn’t applied correctly. Remember, EF is always 3 times BC because of the proportional relationship. Can you revise your calculations?"
If still incorrect: "The correct answer is EF = 3n, where n represents the length of BC."
If the Teacher Provides a Correct Answer:
"Great job! You correctly generalized the relationship as EF = 3n. How might you explain this connection to your students to help them see how algebra relates to geometry?"
