- 3. a rule in geometry that states that the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other sides.
- 5. the distance around the circle
- 7. either of the two sides that form the right angle in a right triangle.
- 8. the ratio of a length in the image to the corresponding length in the original figure.

Down
- 1. describes how much a quantity has changed relative to its original amount. It can be an increase or decrease.
- 2. an equation that relates proportional quantities. We can compare the part to the whole written in the same format as a constant of proportionality: y=mx
