Sum of Supplementary Angles

Supplementary angles are two angles whose measures add up to 180 degrees. This means that when you add the measure of one angle to the measure of the other angle, the total will always be 180 degrees.

Explanation

When two angles are supplementary, it means they form a straight line together. In a straight line, the total angle measure is always 180 degrees. So, when you have two angles that are supplementary, their measures will always add up to 180 degrees.

Example

For example, if one angle measures 60 degrees, then the other angle must measure 120 degrees in order for them to be supplementary. When you add 60 and 120 together, you get 180 degrees, which confirms that they are indeed supplementary angles.

Conclusion

In conclusion, when two angles are supplementary, their measures will always sum up to 180 degrees. This concept is important in geometry as it helps us determine the relationship between angles and solve various problems involving angles.
