- 10. In a right angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.
- 11. An angle whose measure is less than 90°.
- 12. The longest side of a right triangle. The side opposite the right angle.
- 13. A pair of numbers used to locate a point on a coordinate plane
- 14. An angle whose measure is greater than 90° and less than 180°

Down
- 1. f -1(x) is said to be the inverse of f(x) if f(f -1(x)) = f -1(f(x)) = x. It is obtained by interchanging the variables x and y of the function.
- 2. The square root of a number is a value that, when multiplied by itself, gives the number.
