If you are merely drawing from one vertex to all the others, the number of triangles in any n-sided figure is equal to n-2. In this case, a heptagon has seven sides, and thus (7 - 2) = 5 triangles can be drawn.
how many sides does an polygonshave
there can be 13 sides on an isometric drawing

Isometric, orthographic and oblique drawings.
6 sides
A form of three-dimensional projection in which all of the principal planes are drawn parallel to corresponding established axes and at true dimensions; horizontals usually are drawn at 30° from the normal horizontal axes; verticals remain parallel to the normal vertical axis.
the formula is: # of sides x (# of sides - 3) / 2
