If there are n points then the maximum number of lines possible is n*(n-1)/2 and that maximum is attained of no three points are collinear.
False.
If the points are arranged on an imaginary line with one line connecting each point to its neighbor, there will be 99 lines (or line segments).
Any line segment, no matter how short it is, has an infinite number of points.
twenty
Plotting points. Graphing lines, line segments, rays, etc.
8 collinear points determine 28 unique line segments
A triangle
False.
A triangle, but only if the line segments are straight.
fal;se
False.
There is no specific name in general. If the line segments are straight, then it is a triangle.
infinite
If the points are arranged on an imaginary line with one line connecting each point to its neighbor, there will be 99 lines (or line segments).
The answer depends on whether the n points are on a line and you are interested in linear segments or whether they are on the circumference of a circle and you are interested in the number of segments that the circle is partitioned into. Or, of course, any other shape.
That figure is best described as a "triangle".
Any line segment, no matter how short it is, has an infinite number of points.
