What are opposite rays

The video tutorial explains the concept of opposite rays in geometry, highlighting that they are two rays sharing the same endpoint and are collinear, forming a straight line. The teacher revisits the definition of collinearity, emphasizing that collinear points lie on the same line. Through examples, the tutorial demonstrates how opposite rays are drawn and analyzed, ensuring students understand their properties and relationships. The session concludes with a brief Q&A to reinforce learning.
