Exploring Angles: Complimentary, Supplementary, and Vertical

This video tutorial covers three types of angles: complementary, supplementary, and vertical angles. Complementary angles sum to 90 degrees, supplementary angles sum to 180 degrees, and vertical angles are congruent and located on opposite sides of intersecting lines. The video provides definitions, examples, and practice problems for each type, demonstrating how to set up and solve equations to find missing angles.

Which of the following is NOT a type of angle discussed in the video?

• Vertical

• Supplementary

• Complementary

• Acute
