Finding the complement and supplement of two angles

The video tutorial covers the basics of angles, starting with 90 and 180 degree angles, and introduces complementary and supplementary angles. It then transitions to discussing angles in radians, explaining how to calculate complementary and supplementary angles in this unit. The tutorial emphasizes the importance of understanding these concepts for solving geometry problems.
