| coefficient | the numerical factor in any term of a polynomial |
| combination | a group of items in which the order of terms doesn't matter |
| complementary | two angles that sum adds up to 90 degrees |
| congruent angles | angles that have the same measure |
| constant | a term that does not contain a variable in a polynomial |
| coordinate plane | formed by the intersection the x-axis and the y-axis |
| corresponding angles | angles that lie on the same side of the transversal and in corresponding positions |

| fair game | a game in which every player has the same chance of winning |
| hypotenuse | the longest side of a right triangle; opposite of the right angle |
| independent even | when an event happens and it does NOT affect the probability of the occurrence of the other |
