Opposite rays
Two rays that share an endpoint and extend in opposite directions to form a line
Opposite rays are two rays that share the same endpoint. They extend in opposite directions, forming a straight line. Opposite rays are also known as collinear or opposite directions rays.
Opposite rays have these characteristics:
1. They share a common endpoint: Opposite rays have one endpoint in common.
2. They extend infinitely in opposite directions: As they share a common endpoint, one ray extends towards the left while the other ray extends towards the right.
3. They form a straight line: Because they extend infinitely in opposite directions, these two rays form a line.
Opposite rays are often used to define angles or to specify the position of points and objects in geometry. In addition, they help to illustrate different geometric concepts, such as linear pairs and adjacent angles.
