Term | Definition |
---|---|
Midsegment of a triangle | A segment that connects the midpoints of the legs of a trapezoid. |
Coordinate proof | A type of proof that involves placing geometric figures in a coordinate plane. |
Perpendicular bisector | A segment, ray, line, or plane that is perpendicular to a segment at its midpoint. |
Equidistant | The same distance from one figure as from another figure. |
Concurrent | Three or more lines, rays, or segment that intersect in the same point. |
Point of concurrency | The point of intersection of concurrent lines, rays, or segment. |
Circumcenter | The point of concurrency of the three perpendicular bisectors. |
Incenter | The point of concurrency of the three angle bisectors. |
Median of triangle | A segment from one vertex of the triangle to the midpoint of the opposite |
Orthocenter | The point at which the lines containing the three altitudes of the triangle intersect. |
Indirect Proof | A proof in which you prove that a statement is true by tirst assuming that its opposite is true. If this assumption leads to an impossibility, then you have proved that the original statement is true. |
Centroid | The point of concurrency of the three medians of the triangle |
Altitude of a triangle | The perpendicular segment from one vertex of the triangle to the opposite side or to the line that contains the opposite side. |
