Question

This lesson presented complementary and supplementary pairs of angles. One pair adds up to 90º; the other pair adds up to 180º. Here is one way to remember which pair is which. Draw a curve along the letter C in complementary to make a 9 for 90, and add a line through the S in supplementary to make an 8 for 180. How else might you remember that complementary angles total 90º and supplementary angles total 180º? Be creative!
