If you mean within the perimeter of a regular polygon then a polygon with 'n' sides will always have 'n' equilateral triangles within the perimeter. So, an Octagon would have 8. If you are thinking about how many can exist if you do not use the inscribing circles center as a common point for vertices then there would be many more, 3'n'.

Any number................. because it depends on the size of the shape ex. a small octagon can have 20 triangles and a big octagon can have 100 triangles

n-2...
triangle forms 1 (3 sides - 2)
square forms 2 (4 sides - 2)
etc..
from a mathematical perspective, infinitely many. just make triangles within the triangles

infinite. It can be certain only by specifying what kind of triangle you want to form (equilateral, right, isosceles,scalene).

use Combination:
C(n,r) = n!/[(n-r)!r!]
=8!/(5!)(3!)
=(8)(7)(6)(5!)/(5!)(3!)
=56
