[Math4u] petits points?

i had recently , infact yesterday been to an science& math exhibhition.

there was an exhibhit abt some petits points( think the spelling is wrong).

In any plane if we chose n random points then the shortest network between the points is made by lines meeting at a petit point.

i want the proof of two facts abt petit points

1)everyy petit point has 3 lines originating from it at an angle of 120 to each other

2)the number of petit points for the n random points is (n-2)
