If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed

A diagonal of a polygon is a segment drawn from one vertex to another non-adjacent vertex in a polygon. This leaves 32 diagonals that can be drawn from one vertex in a 35 sided polygon.
Number of sides minus two equals number of diagonals drawn from one vertex.
Suppose that the parallelogram is a rhombus (a parallelogram with equal sides). If we draw the diagonals, isosceles triangles are formed (where the median is also an angle bisector and perpendicular to the base). Since the diagonals of a parallelogram bisect each other, and the diagonals don't bisect the vertex angles where they are drawn, then the parallelogram is not a rhombus.
5 triangles are formed.

how many triangles are formed when any parallelogram and it diagonals are drawn
There are 10 possible diagonals drawn from one vertex of the 13-gon which divide it into 11 nonoverlapping triangles.
The number of Diagonals in one vertex of a Triangle is 0 (zero)..
