b. Two perpendicular lines
2. Explain what negative reciprocals are. Give an example.
3. Check the results of Exercise 2 and 4 by graphing the original equation and the answer equation for each example on the same coordinate plane. Describes what happens.
4. Refer to the Activity. Why do you think the right triangle should be scalene?
5. Repeat the activity with a different size right triangle.
a. Are the results different?
b. What do you think would happen if you used a triangle that was not a right triangle?
