Here is a short trick for you to understand the difference between supplementary angles and complementary angles. Tips on Supplementary angles vs Complementary angles Two angles are said to be supplementary if they add up to 180 degrees. Two angles are said to be complementary if they add up to 90 degrees. The supplementary vs complementary angles table. The following table shows the difference between supplementary and complementary angles. These angles have numerous real-time applications, the most common being the crossroads. While supplementary angles add up to 180 °, complementary angles add up to 90°. Supplementary and complementary angles are those angles that exist in pairs. Non-adjacent supplementary angles, when put together, form a straight angle. Hence, these two angles are non-adjacent supplementary angles.

They also add up to 180 degrees, that is, ∠ABC+ ∠PQR = 79 ° + 101 ° = 180 °. Here, ∠ABC and ∠PQR are non-adjacent angles as they neither have a common vertex nor a common arm. Two supplementary angles that are NOT adjacent are said to be non-adjacent supplementary angles. Hence, these two angles are adjacent supplementary angles. They also add up to 180 degrees, that is, ∠COB + ∠ AOB = 70 ° + 110 ° = 180 °. Here, ∠COB and ∠AOB are adjacent angles as they have a common vertex, O, and a common arm OB. Two supplementary angles with a common vertex and a common arm are said to be adjacent supplementary angles. Each of these types of supplementary angles is explained below. So, there are two types of supplementary angles. Supplementary angles can either be adjacent or non-adjacent. Adjacent and Non-Adjacent Supplementary Angles
