Question

How do you remember the difference between supplementary and complementary angles i can never remember what adds up to 90 or 180

Answer 1

Ok this saved me...what I think of is when I give a compliment I high five a person. And when you go for a high five your arm is in a 90 degree angle. Complement = complementary = 90 degrees☺️☺️

Answer 2

remember 90 has 1 p which is complementary and 180 has to p's which is supplementary because 90+90=180 get it?
