6*5/2 = 15.
If each segment intersects exactly two other segment but could, if extended, intersect the third, then the figure is a quadrilateral. Otherwise it is a parallelogram.
collinear means on the same line so they would be collinear if they are on the same line.!
8 collinear points determine 28 unique line segments
True
a triangle
Polygon

No

10 collinear points form one set of overlapping line segments, of which there are 45.
They need not be.
Things in the same plane are coplanar.
Yes, of course, two line segments can be coplanar: Think of the sides of a plane triangle.
A polygon, but only if all the line segments are coplanar.
its a triangle
