Line segment
Yes, I do understand the definition of a line segment. A line segment is a line that actually has two endpoints. Such endpoint is a triangle's or a square's side.
Usually a line segment in a triangle is either assigned a letter, or is referred to by the letters at the end of the segment with a line overhead. For instance, if you have a triangle ABC, you'll have segments AB, AC, and BC. And there would be a line over each segment name.
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side.
A median of a triangle is a line or segment that passes through a vertex and bisects the side of the triangle opposite the vertex.

36. If the length of the line segment joining the midpoints of two sides of an equilateral triangle is 6 the perimeter of the triangle is 36.
