# 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.
• Type of point to locate:

( If you choose several types, the server will randomly pick one among them at each shoot.)
• Number of shots in one session , , , , ( The score is given only at the end of a session.).
• Size of the picture :    ( The bigger is the picture, the harder is the exercise.)
