| Term | Definition |
|---|---|
| Altitude of a triangle | Perpendicular segment from a vertex of the triangle to the line containing the opposite side |
| Centroid | Point of concurrency of the medians |
| Circumcenter of a triangle | Point of concurrency of the perpendicular bisectors of a triangle |
| Concurrent | When three or more lines intersect at one point |
| Equidistant | Same distant from the objects |
| Incenter | Center of a circle inscribed in a triangle |
| Indirect proof | A proof involving indirect reasoning |
| Median | Segments whose endpoints are a vertex and the midpoint of the opposite side |
| Mid-segment of a triangle | Segment connecting the midpoints of two sides of a triangle |
| Orthocenter | A point the lines that contain the altitudes of a triangle are concurrent at |
| Distance from a point to a line | Length of the perpendicular segment from the point to the line |
