Adjacent non-supplementary angles

The red lines represent an adjacent non-supplementary angle. It isn't supplementary because the two angles don't form a line and they are adjacent because one side is shared and they have the same vertex. Clocks are an everyday use and I usually check the clock more than once for each class. We can also use clocks to find angle measures in geometry class.
