| Term | Definition |
|---|---|
| Altitude of a Triangle | A straight line through a vertex and perpendicular to (i.e. forming a right angle with) a line containing the base (the opposite side) of a triangle |
| Angle bisector theorem | Concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle. |
| Angle bisector theorem, converse | If a point is equidistant from the sides of an angle, then it is on the angle bisector. |
| Center of a Polygon | In a rotation, the point that does not move. The rest of the plane rotates around this one fixed point. |
| Centroid of a Triangle | The point where the three medians of the triangle intersect |
| Circumcenter of a triangle | The point where the three perpendicular bisectors of a triangle meet |
| Circumscribed | A geometric figure that is drawn around another geometric figure so as to touch all its vertices |
| Conditional probability formula | The conditional probability of A given B is denoted by P(A|B) and defined by the formula P(A|B) = P(AB) P(B) , provided P(B) > 0. (see also probability formula) |
| Experimental probability | The ratio of the number of times the event occurs to the total number of trials (see also complement probability, conditional probability, probability, theoretical probability) |
