Use the formula n(n-1)/2 --> 7(7-1)/2 = 7(6)/2 = 42/2 = 21.
there are infinitely many segments in a line.
Line segments are lines so the answer is 3.
A circle does not have line segments. It is a continuous curve.

There can only be one line segment between two points. If you only have two points, there's no way to create more than one line from one to the other without adding another point.
If it was an heptagon it would have 14 diagonals
Each point can be connected to every other point. That gives you 10 x 9. However, since this counts each line segment twice, this result should be divided by 2.
10 collinear points form one set of overlapping line segments, of which there are 45.
depend how many points are them

Only one line can be drawn through eight points.
45 points
Use the formula n(n-1)/2 --> 7(7-1)/2 = 7(6)/2 = 42/2 = 21.
No, because then it would become many line segments.
