Complementary angles are two angles that add up to 180 degrees. They are opposite each other, and their angles add up to the same value.
Supplementary angles are two angles that add up to 180 degrees. They are adjacent, and their angles add up to the same value.
Examples:
If angle A is 45 degrees, then angle opposite it is also 45 degrees.
If angle B is 70 degrees, then angle adjacent to it is also 70 degrees.
If angle C is 110 degrees, then angle D and angle E are both 110 degrees.
Remember, complementary and supplementary angles are not the same thing! They are two distinct types of angles with different measures
