How to graph with triangles?

1
I would like to know if there is a possibility of using the chart and making triangles in it by passing the 3 coordinates to generate the triangles, as in the image:

(Do not call the image I did just an illustrative schematic in the paint rapidão here)

Well if there is a possibility, and someone can give me some material or example of how to do it, I thank you.
