9 (two less than the number of vertices in the polygon).
A parallelogram can be divided into two triangles by drawing a diagonal. Conversely, two triangles can be combined to form a parallelogram. Therefore, the number of distinct parallelograms that can be formed from triangles depends on the number of triangles available and how they are arranged, but at least two triangles are needed to create one parallelogram.

To create a row of 6 triangles, each triangle can be formed using 3 line segments. However, since the triangles share sides, the total number of segments needed will be fewer than 18 (6 triangles × 3 segments each). Specifically, for 6 triangles arranged in a row, you need 10 segments: 3 for the first triangle, 1 additional for each of the 5 shared sides between the triangles, and 3 for the last triangle. Thus, the total number of line segments needed is 15.

There are 4 triangles in a 6 sided hexagon
A minimum of 2 triangles are needed, but you can also make a rectangle with 3 or more triangles.
There are two ways to think of this question, if the triangles don't have to intersect then the answer is zero. If the triangles have to intersect, then the minimum number of points is one, if the triangles meat at vertex to edge or vertex to vertex.
The minimum number of seismographs needed to locate an epicenter of an earthquake is 3.
