Triangle

Triangles are defined by 3 points in the XY plane, which is a total of 6 parameters:
| Parameter # | Description | Face Name | Face # |
| 1 | The X coordinate of vertex 1. | All Faces | 0 |
| 2 | The Y coordinate of vertex 1. | All Faces | 0 |
| 3 | The X coordinate of vertex 2. | All Faces | 0 |
| 4 | The Y coordinate of vertex 2. | All Faces | 0 |
| 5 | The X coordinate of vertex 3. | All Faces | 0 |
| 6 | The Y coordinate of vertex 3. | All Faces | 0 |
The reference point is the (0, 0, 0) coordinate, which may not be part of the triangle at all; depending upon the values give for the vertex points. Face Numbers: All faces Face 0.
