1 . coplanar points point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively.
2 . betweenness of points a set of two or more points all on the same line.
3 . length of a segment a set of two or more points all on the same plane.
4 . opposite rays the set of all possible points.
5 . space a line or segment that intersects the segment at its midpoint.
6 . collinear points the distance between the endpoints of a segment.
7 . line segment the set of two different endpoints and all points between them.
8 . bisector of a segment the point on a segment that divides the segment into two equal segments.
9 . midpoint of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c.
10 . ray a ray, , is the set of points beginning at point a and going infinitely in the direction of point b.
