The video tutorial explains how to find unknown angles in a geometric shape by setting up and solving equations. It demonstrates that the sum of angles in a quadrilateral is 360 degrees and shows how to solve for an unknown angle x. The tutorial also covers how to determine if lines are parallel by checking if angles are supplementary, using examples to illustrate these concepts.
