| A | B |
|---|
| altitude | in a polygon a line drawn from any vertex to any side so that the line is perpendicular to the side to which it is drawn |
| direct proportion | a method for comparing two equal ratio Example: 2/3 = 4/6 |
| extrapolate | to make a guess based on known information and observation |
| identity property | for any number in addition "a + 0 = 0 + a = a; in multiplication " a x b = b x a = a" |
| irrational Numbers | any number that can not be take out of a "radical" (like the "square root") |
| rational number | a number that can be formed as a ratio of two intergers; therefore, it is a "fraction" (example: 3/4) |
| real number | a number that is either a fraction or an interger - is a set of "real numbers" (examples: -2; 0; 0.15; 1/2; "the square root of 3" is not a rational number but an "irrational number"; pie (3.14) is a rational number and 7.89 x 10 to the ninth power is also a rational number |
| slope | the amount of change in the "y-coordinate" with respect with the amount of change in the "x-coordinate" in a straight line on a graph |
| zero property | for any number "a" in addtion, "a + 0 = a" and multiplication "a x 0 = 0" |
| function | a relation such as a graph in which a variable is dependent is dependent upon another value - in a graph each value of "x" corresponds to a unique of "y" |
| "tranlation" silding motion | moving of a figure along the "x-axis" from "left to right" or from "right ot left" |
