A pair of opposite rays are two rays that have the 'same endpoint and extend in opposite directions. Ray has two end points. When are two lines not coplanar. Opposite math rays are rays with a common endpoint, extending in opposite directions and forming a line. Two rays that share the same endpoint form an angle with each other. Figure 10 compares the geometric representation of rays, lines, and segments. Take an example of the below Opposite Rays: The start point for the Rays ZXandZYisZ, and then they both go the opposite direction that makes 2 opposite rays: ZX and ZY. They are represented by a segment with an endpoint at one extremity and an arrow (showing direction) at the other extremity. If we had a line so it extends infinitelyin either direction, and I pickedan end point somewhere, and I erased everythingthat extended beyond thatend point, what I've justcreated is a ray.So a ray has one end point and it extendsinfinitely from that end point.But how do you label a ray?Well, you start off by sayingwhat is your end point?My end point of this ray is A because that'swhere it starts, and it extendsthrough point B. like the sun is the end point but it puts out rays everywhere, so when you have two points you can know in what direction a single ray is going. Explanation. Opposite Rays: 2 rays that lie on the same line, with a common endpoint and no other points in common. Skew lines are lines that are not in the same plane.
