Exploring Complementary and Supplementary Angles

In this video, Mr. J explains complementary and supplementary angles. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. The video includes examples of finding missing angles for both types. Mr. J also provides a mnemonic to help remember the difference between complementary and supplementary angles.

• 180 degrees

• 360 degrees

• 90 degrees

• 45 degrees
