Adjacent non supplementary angles

This is a picture of a roller coaster which has adjacent non supplementary angles. Adjacent angles are angles that share a vertex and a side, and non supplementary means that the sum of the angle measures can't add up to 180 degrees. In the picture angle 1 and 2 are adjacent because they are next to each other but are both acute angles so they can't add up to 180 degrees. Roller coasters are found usually in amusement parks and either scare people or give them a rush of fun. Constructual engineers, physicists, and amusement park ride control people work with roller coasters.
