Adjacent Angles and Their Properties

The video tutorial introduces the concept of adjacent angles, which are two angles sharing a common side and vertex. It explains how to identify them using an example with angles of 70° and 30° sharing a vertex at point R and a common side RA. The tutorial concludes by summarizing the key points about adjacent angles.
