Exploring the Angle Addition Postulate

The video tutorial covers the angle addition postulate, explaining how the sum of two smaller angles equals the larger angle. It includes examples and algebraic applications, such as using angle bisectors. The segment addition postulate is also introduced, showing how the sum of smaller segments equals the whole segment. The tutorial emphasizes solving problems using these postulates and algebraic expressions.
