The video tutorial explains the concepts of complementary and supplementary angles. It clarifies that complementary angles add up to π/2, and if one angle is greater than π/2, they cannot be complementary. The tutorial then demonstrates how to calculate supplementary angles, which add up to π, using an example where one angle is 2π/3, resulting in the other angle being π/3.
