Geometrical combinatorics

Please throw some light on counting k-sided polygon in an n-sided polygon under different conditions viz how many triangles can be drawn using vertices of a 15 sided polygon if none of the sides of the polygon is also side of the triangle and in similar way how to find out number of hexagons,equilateral triangles,isosceles triangles etc.
