A look at the relationship between sides of a right triangle.

Notice that the triangle is a right triangle, a triangle with a 90 degree angle.
1. In the spreadsheet, do you notice any relationship between a^2, b^2, and c^2? If so, what is it?
2. In the field where the points are displayed, double click on Point A and change its y-value. Now look back at the spreadsheet. Repeat the process a few times. Is the relationship still the same?
3. Now change the value of x for Point B in the field where the points are displayed. Now look back at the spreadsheet. Repeat the process a few times. Is the relationship still the same?
4. Now double click on Point C in the field where the points are displayed. Change either x, y, or both. Now look back at the spreadsheet. Is the relationship still the same?
