| Absolute value | A number’s distance from zero on a number line. |
| Altitude (of a triangle) | A segment drawn from a vertex of a triangle and perpendicular to the opposite side or to the line containing the opposite side. |
| Analytic geometry | A branch of geometry in which points are represented with respect to a coordinate system, and in which the approach to geometric problems is primarily algebraic. |
| Angle bisector | A ray in the interior of an angle, whose endpoint is the vertex of that angle, and divides the angle into two congruent angles. |
| Arc | A continuous part of a circle between two points on the circle. |
| Binomial | A polynomial with two terms (e.g., 7a + 4b). |
| Central angle of a circle | An angle whose vertex is the center and whose sides are the radii of the circle. |
| Central angle of a regular polygon | An angle whose vertex is the center and whose sides intersect the regular polygon at adjacent vertices. |
| Circumscribed polygon | A polygon that surrounds a circle with each of its sides tangent to the circle. |
| Dependent events | Two events in which the outcome of one event affects the outcome of the other event. |
| Direct proportion | Two quantities that always have a constant ratio |
| Exponential function | A function that can be described by an equation of the form y = ax, where a > 0 and a does not equal 1. |
| Inscribed angle | An angle whose vertex is on the circle and whose sides are chords of the circle. |
| Inscribed polygon | A polygon surrounded by a circle, where each of its vertices fall on the circle. |
| Interquartile range | The difference between the first and third quartile. |
