Finding the distance between two points using the Pythagorean Theorem Standard 8.2G Sarah is walking in her neighborhood. She walks from her house 15 yards east to the park. Then she walks 50 yards north to the grocery store. What is the distance it would have taken Sarah if she went directly from her house to the store without stopping at the park?

PowerPoint Presentation:

Sarah is walking in her neighborhood. She walks from her house 15 yards east to the park. The she walks 50 yards north to the grocery store. What is the distance it would have taken Sarah if she went directly from her house to the store without stopping at the park? Steps Work 1. Draw a diagram. 2. Use the Pythagorean Theorem. 3. Identify legs and hypotenuse sides. 4. Plug in all known distances between each point for A and B 5. Multiply A times itself. Then B times itself. 6. Add A plus B together to get C Squared. 7. Find the exact square root of C squared . 1. 3 . A=Distance from Sarah’s house to the park 5. 15x15=225 or 15²=225 50x50=2,500 or 50²=2,500 6. 225+2,500=2,725 Answer: It would take Sarah about 52.2 yards if she went diagonally across to the grocery store. B=Distance from the park to the store. C=unknown distance from her house to the store 4. A=15 B=50 C=? 15²+50²=C squared
