not in euclidean geometry (I don't know about non-euclidean).
frequency polygon
No, because if there is more than one midpoint then it will be like multiple line segments connected together. You can't have two midpoints or more, but you can have one to divide the line segment in half.
The Centroid is the point that is created when the midpoints of each side are connected with a straight line to the opposite vertex, or corner.Centroid Facts:Always inside the triangle.Each side of the triangle is divided into two equal segments.
Diagonals between two opposite corners, and a vertical line between midpoints of 2 opposite sides, and a horizontal line between midpoints of the other pair of sides.
The straight line does not have a specific name.
No, it can only have one midpoint, because if it had two midpoints, then there would be two line segments! Also, if you add two midpoints, then thus creating another segment.

Three pairs. The line joining the midpoints of any two sides of a triangle is always parallel to the third side of the triangle (and half its length).
It forms a parallelogram.
because a line is just a collection of points
A line that connects the midpoints of a figure is a midsegment.

an intersecting line segment is when two line segments cross together
Two line segments of the same finite size.
