These two angles (140° and 40°) are
Supplementary Angles, because they add up to
180°. Notice that
together they make a straight angle.
But the angles don't have to be
together.These two are supplementary because 60° + 120° = 180°
Two Angles are Supplementary if they add up to 180 degrees.
What are Supplementary Angles ?

WHAT ARE COMPPLEMENTARY ANGLES ?
These two angles (40° and 50°) areComplementary Angles, because they add up to 90°. Notice that together they make a right angle .
But the angles don't have to be together.These two are complementary because 27° + 63° =
90°

Complementary angles VS Supplementary Angles
A related idea is Supplementary Angles - those add up to 180° How can you remember which is which? Easy! Think:•"C" of Complementary stands for "Corner" (a Right Angle), and •"S" of Supplementary stands for "Straight" (180 degrees is a straight line)Or you can think: when you are right you get a compliment (sounds like complement).Or you could also think: "Supplement" (like a Vitamin Supplement) is something extra, so it it bigger.
