9: the square root of 9 is 3.
25: the square root of 25 is 5.
36: the square root of 36 is 6.
81: the square root of 81 is 9.
144: the square root of 144 is 12.

If you are considering all the vertices independently you will have a total of 8*10 = 80 triangles. You can figure out this way: the sum of the interior angles of a decagon = (2n-4)*right angles or (n-2)*triangles. So a decagon will form 8 triangles.
hope this helps...
