Find the complementary and supplementary angles for an angle greater than 90 degrees

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.

What is the relationship between supplementary angles and their sum?

How can you verify that your calculated angle makes sense in the context of π?
