What is supplementary?

In geometry, supplementary angles are two angles whose measures add up to 180 degrees. If two angles are supplementary, one is said to be the supplement of the other.

Here are some key aspects of supplementary angles:

• Definition: Two angles are supplementary if their measures sum to 180 degrees.
• Linear Pairs: Supplementary angles often form a <a href="https://www.wikiwhat.page/kavramlar/Linear%20Pair">linear pair</a> when they are adjacent (share a common vertex and side), forming a straight line.
• Non-Adjacent Angles: Supplementary angles do not necessarily need to be adjacent. Two non-adjacent angles can still be supplementary if their measures sum to 180 degrees.
• Examples: An angle of 120 degrees and an angle of 60 degrees are supplementary because 120 + 60 = 180. An angle of 90 degrees and an angle of 90 degrees are also supplementary.
• Relationship to other angles: Understanding supplementary angles is important when studying <a href="https://www.wikiwhat.page/kavramlar/Complementary%20Angles">complementary angles</a> (angles that sum to 90 degrees) and other geometric relationships.
