Triangular shoot --- Introduction ---

A triangle has 4 centres: barycenter, orthocenter, incenter and circumcenter.

If you think you know these centers well, try this exercise/game: we show you a triangle, and you should locate one of its centers by shooting on it (click on the picture). Or on the contrary, we show you two of the vertices of the triangle as well as a center, and you shoot on the missing vertex.

You may choose what you want to do.
