The description seems a bit confusing (to me) but it sounds like it could be a perpendicular bisector of a side of a triangle.
All of the points on a perpendicular bisector are equidistant from the endpoints of the segment.
This would depend on if you use the segment's endpoints on the triangle with the vertex of the triangle to get the angle.
-- If both of its endpoints are the same vertex, then the line segment's lengthis zero, and you'd look at it and swear that it was only a point, and you can'tsee it at all if you don't know it's there.-- If each of its endpoints is a different vertex, then the line segment exactlycoincides with one side of the triangle, and you can't see it at all if you don'tknow it's there.
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side.
median
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.
endpoints!! endpoints!!
two endpoints
a line segment is part of a line that does not continue infinetely. therefore it has endpoints on both sides. by default a line segment has 2 endpoints, it is not a question if it 'can' have 2 endpoints.
segment or line segment.
A line segment has two endpoints.
A chord is a line segment whose endpoints lie on a circle. A secant is a line (or line segment) that intersects a circle in two places, endpoints NOT on the circle.
