adjacent non supplementary angles

This is an image of fingers that could be stuck on a scare crow. Scare crows are often seen on farms or sometimes in yards. They are used to scare off birds because they think it's a human. The fingers on the scare crow act like adjacent non supplementary angles. Adjacent non supplementary angles are angles that share a common vertex and a side. The three sticks creating the scare crow's fingers make two adjacent angles. This is an image I took myself.
