First choose a diagonal. In 9 ways. Then choose any other point. 4 points left. Can be chosen in 4 ways. Therefore. 36 trangles/3 because of repitition.

Answer is hence 12.

REpitition is because you can land up with the same triangle in three different ways (through the given points/ diagonals again)
