Angles and Circle Relationships

The video tutorial explains the angles outside the circle theorem, which involves three scenarios: a tangent and a secant, two tangents, or two secants intersecting outside a circle. The measure of the angle formed is half the difference of the intercepted arcs. The video provides examples to illustrate how to apply the theorem to solve for unknowns, such as finding the value of x or the measure of an intercepted arc.
