Draw at the center of a triangle (Tikz)

How can I draw a label at the center of a triangle without drawing the triangle itself?

I don't want the drawing of the triangle to interfere with other drawing elements, so I only want the label.

• Depends on what you call the center of a triangle. If it's the isobarycenter, so Ignasi's answer is the best (and the shorter). If you want to display other centers, you should use tikz-euclide library which allows you to find all kind of centers in a triangle. Apr 19 '21 at 15:28
