Using Angle Facts

The video tutorial covers solving math problems using angle facts. It is divided into four parts: writing algebraic equations to find the values of x and y, and solving these equations. The tutorial explains how to use straight and vertical angles to form equations and solve for unknown variables. The video concludes with a summary of the concepts discussed.
