The video tutorial explains the concept of exterior angles in triangles, showing how to extend a side to form an exterior angle and how it relates to the interior opposite angles. It provides examples to illustrate that the exterior angle equals the sum of the interior opposite angles and is greater than each of them. The tutorial also covers the linear pair relationship between the exterior angle and its adjacent interior angle, and includes problem-solving exercises to reinforce understanding.
