Solving for Missing Angles in Geometry

This video tutorial teaches how to solve for missing angles by exploring two cases: complementary angles, which add up to 90 degrees, and supplementary angles, which add up to 180 degrees. The video provides step-by-step examples for each case, demonstrating how to calculate the missing angle by subtracting the known angle from the total degrees required for complementary or supplementary angles.

What is the total degree measure that complementary angles sum up to?

• 45 degrees

• 360 degrees

• 180 degrees

• 90 degrees
