Terms | Definitions |
|---|---|
 acute angle | An angle measuring more than zero degrees and less than 90 degrees |
| congruent | Having the same size and shape |
| difference | The amount that remains after one number has been subtracted from another |
| exponent | A number that tells how many times the base is multiplied by itself |
| reciprocal | The inverse of a fraction; when multiplied by the original fraction, it results in a product that equals one |
| vertex (vertices - plural) | The point of intersection for two sides of a plane figure, three sides of a solid figure, or the endpoints of two rays that form an angle. |
| expression | A combination of numbers and variables connected by one or more operations signs |
| polygon | Three or more line segments in a plane that forms a closed figure. The line segments never cross but meet at their endpoints. |
| product | The result of muliplying two or more numbers |
| hexagon | A polygon with six sides. |
| range | The difference between the least and greatest values in a set of numbers |
| scalene triangle | A triangle with sides of different lengths and no two angles are the same |

| perimeter | The distance around a figure |
| circumference | The distance around a circle (the perimeter of a circle) |
| straight angle | An angle that measures 180 degrees |
| obtuse angle | An angle measuring more than 90 degrees and less than 180 degrees |
| complementary angle | Two angles whose sum equals 90 degrees |
| diameter | A line segment that passes through the center of a circle and has its endpoints on the circle |
| sum | The total of two or more numbers being added |
| quotient | The result of dividing one number by another; the solution to a division problem |
| dividend | In a division problem, it's the number being divided |
| divisor | In a division problem, the number that an amount is divided by |
| mean | The sum of a group of numbers divided by the number of numbers; also known as the average |
| median | A value found by ordering a group of data from least to greatest and choosing the middle value of the group. |
| mode | In a group of values, the value that occurs most often |
| pyramid | A solid figure that has triangles for its sides and a polygon as its base |
| quadrilateral | A polygon that has four sides |
| parallelogram | a quadrilateral with two pairs of congruent, parallel sides |
| rectangle | A parallelogram with four right angles |
| reflection | A mirror image of a figure shown over a line of reflection |
| rate | A ratio that compares two different types of quantities |
| equation | A mathematical sentence that uses an equal sign |
| scale drawing | A drawing of an object that is different in size (usually smaller than the original) but keeps the same proportions |
| trapezoid | A quadrilateral with one pair of parallel sides |
| cylinder | A solid figure with two congruent and parallel circular bases |
| octagon | An eight-sided polygon |
| pentagon | A polygon with five sides |
| percent | The ratio of a number to 100 (per one hundred); the symbol % |
| similar figures | Figures that have the same shape but different sizes; their sides are proportional, while their corresponding angles are equal |
| equilateral triangle | A triangle that has three equal sides and three equal angles |
| radius | A length that is half the diameter of a circle; the distance from the center of the circle to the circle itself |
| isosceles triangle | A triangle with two equal sides and two equal angles |
| right triangle | A triangle with one right angle |
| supplementary angles | Two angles whose sum is 180 degrees |
| order of operations | Rules that tell which steps to follow when solving an expression |
| rhombus | A parallelogram with all sides equal and congruent |
| lowest terms | A fraction with all common factors (other than 1) factored out of the numerator and denominator |
| square root | A number that when multiplied by itself results in the original number |
| prism | a solid figure that has two congruent, parallel polygons as its bases. Its sides are parallelograms. |
| ratio | A comparison of the two values of two numbers |
| proportion | An equation stating that two ratios are equal |
| simplify | To make a fraction easier to work with by taking out common factors |
| unit ratio | A ratio that shows the cost per unit of measure |
| quadrant | One of the four regions formed by the intersection of the axes of a coordinate graph |
| x-axis | The horizontal number line of a coordinate graph |
| y-axis | The vertical number line of a coordinate graph |
| x-coordinate | The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair. |
| y-coordinate | The value on the y-axis used to locate a point on the coordinate graph. It is the second value in an ordered pair. |
| ordered pair | Two numbers listed in a specific order; it describes a point on the coordinate graph |
