The video tutorial explains the concept of adjacent angles, emphasizing that they share a common vertex and side. It provides examples such as angles CDE and CDA, and angles BFD and BFC, to illustrate these points. The tutorial also covers the naming conventions for angles, highlighting the importance of the vertex being the middle letter. Further examples, like angles FGH and EGH, are used to reinforce the understanding of common sides and vertices. The session concludes with a brief mention of additional examples that could be explored.

What is a key characteristic of adjacent angles?
