2 angles are complementary if they add to 90 degrees. For example: 52 and 38 are complementary because 52+38=90 degrees. Similarly, 2 angles are supplementary if they add to 180 degrees.

Definition of Complementary Angles: Two angles are complementary if and only if the sum of their degree measures is 90. If two angles are complementary, then each is said to be a complement of the other. Complementary angles do not have to share the same vertex or a common side.

1. Complementary Angles: Two angles whose sum is 90° (that is, one right angle ) are called complementary angles and one is called the complement of the other.

Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle. But the angles don’t have to be together.

Complementary angles are pair angles with the sum of 90 degrees. Three angles or more angles whose sum is equal to 90 degrees cannot also be called complementary angles. Complementary angles always have positive measures. it is composed of two acute angles measuring less than 90 degrees.

Complementary angles are those angles whose sum is equal to 90^{o}. Explanation: Angle equal to 90^{o} is called right angle. Sum of two right angles is 180° which is double the sum of two complementary angles. Hence, it is not possible for two right angles to complement each other.

Two angles are called complementary when their measures add to 90 degrees.

These pairs are called vertical angles, and they always have the same measure. ∠1 and ∠3 are vertical angles.

Special names are given to pairs of angles whose sums equal either 90 or 180 degrees. A pair of angles whose sum is 90 degrees are called complementary angles. Each angle is the other angle’s complement. Likewise, if two angles sum to 180 degrees, they are called supplementary angles.

In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they “Complement” each other. because the right angle is thought of as being a complete angle.

∴Sum of two acute angles cannot make a supplementary angle. As we know that obtuse angle is always greater than 900. So, the sum of two obtuse angles always makes greater than 1800. ∴Sum of two right angles always makes a supplementary angle.

You may even have learned about straight and reflex angles, but if you are angling to learn even more, you can investigate many other kinds of angles like exterior and interior angles. You can learn about congruent, adjacent, vertical, corresponding, and alternating angles, too.

Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees.
