WebSupplementary angles are two angles whose sum is equal to \begin{align*}180^\circ\end{align*}. These two angles are supplementary because … WebAngles on one side of a straight line always add to 180 degrees Example: 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one. Example: We know one angle is 45°, what is the other angle "a" ? Angle a is 180° − 45° = 135° This method can be used for several angles on one side of a straight line.
