| height | the measurement from top to bottom |
| inequality | A mathematical expression which shows that two quantities are not equal. |
| length | distance from one end to the other |
| linear function | A function that can be written in the form y=mx + b, where x is the independent varible and m and b are real numbers. Its graph is a line. |
| mean | In a data set, the sum of all the data points, divided by the number of data points; average. |
| median | The middle number in a data set when the data are put in order; a type of average. |
| midpoint | A point on a line segment that divides the segment into two congruent segments. |
| mode | A type of average; the number (or numbers) that occurs most frequently in a set of data. |
| net | flat shape which can be folded up into three dimensional solid |
| origin | the point of intersection of the x and y axis on a coordinate or Cartesian plane |
| parallel | Two lines are parallel if they are in the same plane and never intersect. |
| percent | A fraction, or ratio, in which the denominator is assumed to be 100. The symbol % is used for percent. |
| perimeter | The sum of the lengths of the sides of a polygon. |
| perpendicular | Two lines are perpendicular if the angle between them is 90 degrees. |
| radius | The distance from the center to a point on a circle; the line segment from the center to a point on a circle. |
| range | In statistics, the difference between the largest and the smallest numbers in a data set. |
| rate | A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable. |
| real number | The combined set of rational numbers and irrational numbers. |
| rectangle | A quadrilateral with four 90-degree angles. |
| rhombus | A parallelogram with four equal sides. |
