- TriangleCenter[ <Point>, <Point>, <Point>, <Number> ]
- gives n-th triangle center of triangle ABC. Works for n < 3054.
- Example:Let A = (1, -2), B = (6, 1) and C = (4, 3).
TriangleCenter[A, B, C, 2]yields the centroid D = (3.67, 0.67) of the triangle ABC.
Some common triangle centers
| Index n | Center |
|---|---|
| 1 | Incenter |
| 2 | Centroid |
| 3 | Circumcenter |
| 4 | Orthocenter |
| 5 | Nine-point center |
| 6 | Symmedian point |
| 7 | Gergonne point |
| 8 | Nagel point |
| 13 | Fermat point |
