Exploring Supplementary and Complementary Angles

The video tutorial covers the concepts of complementary and supplementary angles in geometry. It explains that complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. The tutorial provides examples and demonstrates how to find missing angles using subtraction. Students are encouraged to participate and solve problems to reinforce their understanding.

What is the sum of complementary angles?

• 360 degrees

• 45 degrees

What mnemonic can help remember the difference between complementary and supplementary angles?

• C for corner, S for straight

• C for circle, S for square

• C for curve, S for straight line

• C for corner, S for side

How can you identify a right angle?

• It forms a square in the middle
