There are 3 triangles inside a 5 sided pentagon polygon
There are 20 triangles inside a 22 sided polygon
Any n-sided polygon (n being any integer) will always have a minimum of n-2 triangles inside the shape, assuming that the polygon is regular with no reflex angles.
there r 800 vetices in three triangles
There are a number of different, and sometimes overlapping, classifications. Polygons may be convex or concave. In a convex polygon, any two points inside the polygon are joined by a straight line that is wholly inside the polygon. In a concave polygon there are at least two points such that the line joining them intersects its boundary. Polygons can by equilateral (all sides of equal length), or equiangular (all angles of equal measure) or regular (all sides equal AND all angles equal). Note that in general (unlike for triangles) equilateral and equiangular are not the same. Polygons can be classified according to the number of sides/angles.

Rhombus
There are: 63-2 = 61 triangles
True
20 triangles will fit into a 22 sided polygon whose interior angles add up to 3600 degrees
yes, I just don't know why, but they can

The total angles will be 3600 degrees, because each triangle will have 180 degrees total.
Any n-sided regular polygon, by joining a single vertex up to each of the others, will have a total of (n - 2) triangles inside. In this case, an 11-sided polygon will contain 11 - 2 = 9 triangles.
