Non Congruent Interior Angles

This is an Hand M sign. Signs are used as marketing or advertising. Advertising is a way to attract customers. In order to attract customers you have to have a sign that tells them where the store is, thats why people use signs. Signs are found everywhere, some example are stop signs, store signs, and street signs. Signs help people to find their way around. In this particular sign I found non congruent interior angles in the M in Hand M. I highlighted the angles in blue, these two angles are not congruent because they are not the same size.
