1. Adjust the triangle to a size and angle of your choice. Record the length of each leg of the triangle. Then adjust the size of the triangle (either making it larger or smaller) by moving the slide; be sure not to change α. Record the new leg lengths.
a) Set up a proportion comparing the leg lengths between the two triangles
b) How does our answer from part (a) support what we have learned thus far about triangles?
2. Repeat the process you carried in question 1, but this time change the size of α by moving C up and down, but leaving the slide alone. Can you a set up a proportion comparing the side lengths of the new triangles you made? If not, explain why this may be the case.
3. What generalizations can we develop from this information? (Hint: Think about how changing the angle size effects the ratio between the side lengths)
