Determine how to use angle relationships to solve for the missing angle

The video tutorial demonstrates how to find a missing angle in a triangle using angle relationships and the triangle sum theorem. It begins by identifying the problem and the presence of parallel lines, which leads to exploring angle relationships such as vertical and alternate interior angles. The tutorial then applies these relationships to calculate the missing angle, concluding with the use of the triangle sum theorem to verify the solution.

Explain how vertical angles can help in finding the measure of an angle.
