Complementary and Supplementary Angles

The video tutorial explains how to find the complement and supplement of an angle, specifically 85 degrees. It begins by defining complement angles as those that add up to 90 degrees and calculates the complement of 85 degrees as 5 degrees. It then defines supplement angles as those that add up to 180 degrees and calculates the supplement of 85 degrees as 95 degrees. The tutorial concludes by highlighting the differences between complement and supplement angles and provides a brief summary of the calculations.
