## supplementary angles

### Supplementary angles are a pair of angles whose sum is equal to 180 degrees

Supplementary angles are a pair of angles whose sum is equal to 180 degrees. In other words, if you have two angles that are supplementary to each other, when you add their measures together, the total will be 180 degrees.

For example, if we have an angle with a measure of 60 degrees, its supplementary angle would measure 120 degrees, because 60 + 120 = 180.

Supplementary angles can be formed by two angles that share a common side and a common vertex, but their other sides lie on opposite sides of a straight line. This means that when you extend one side of an angle, it forms a straight line with the other angle’s side.

Supplementary angles can also be formed by two angles that are adjacent (next to each other) and their non-common sides form a straight line.

It’s important to note that supplementary angles do not have to be adjacent or in any specific positions relative to each other. As long as their measures add up to 180 degrees, they are considered supplementary angles.

Supplementary angles can be useful in geometry, trigonometry, and other areas of mathematics where angle relationships and measurements are involved.
