Exploring the Vertical Angle Theorem

This video tutorial from YourTeacher.com demonstrates how to solve a geometry problem involving vertical angles. The problem requires finding the value of x and the measures of angles POS and QOR using a given diagram. The tutorial explains that since angles POS and QOR are vertical angles, their measures are equal. An equation is set up and solved to find x, and then the measures of the angles are calculated by substituting x back into the expressions for the angles.
