When one point is placed on a line, a ray is produced. A ray has one endpoint and goes on forever in one direction. When two points are placed on a line, a line segment is produced. A line segment has two distinct endpoints. It is a portion of a line. Line segments can be ...
A line segment is a piece of a line with two endpoints and a definite length. A bisector is a line, line segment, ray, or point that cuts something exactly in half. So, a segment bisector is a line, line segment, ray, or point that cuts a line segment exactly in half. Point C ...
Because a line segment has a beginning and an ending point, its length can indeed be measured, and we can compare the two in its terms. On the other hand, a line can be drawn continuously in either direction, which means that there is no end or start to it, whereas a ray has a ...
