Across
- 7. The side of a right triangle opposite the right angle. It is the longest side of the triangle.
- 9. The set of all real numbers that can be expressed as the quotient of two integers where the denominator is nonzero.
- 10. The set of real numbers that cannot be expressed as the quotient of two integers with a nonzero denominator.
- 14. The inverse of a number where the numerator of the original becomes the denominator of the reciprocal, as well as the denominator becoming the numerator. When added together, the original number and reciprocal will always equal 1.
- 16. Equal in size and shape.
Down
- 1. A mathematical equation containing one or more variables. Algebraic equations must contain either an equal, greater than, or less than sign to be considered an equation.
- 2. A symbol that represents a quantity that can change (a variable quantity).
- 3. The four sections into which the coordinate plane is divided by the x and y axes.
- 4. A number or fraction used to indicate the steepness and direction of a line.
- 5. – A mathematical expression which can contain numbers, variables, or operators. However, it cannot contain equal, greater than, or less than signs.
- 6. A closed geometric figure where all sides are line segments.
- 8. A ratio that compares two quantities that have different units of measure.
- 11. The quotient of two numbers or expressions, often expressed as a proportion.
- 12. Coordinates (0, 0) on the coordinate plane. It is the intersection of the x and y axes.
- 13. The symbol (√) used to notate nth roots.
- 15. The result of raising a base (number with an exponent attached) to an exponent.
