Concave polygon does not contain all other vertices in its edges and interior. The convex hull of the concave polygon's vertices, and that of its edges, contains points that are exterior to the polygon. Concave polygon A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have at least one reflex interior angle—that is, an angle with a measure that is between 180 degrees and 360 degrees exclusive. Some lines containing interior points of a concave polygon intersect its boundary at more than two points. Some diagonals of a concave polygon lie partly or
Mickey Mouse degrees of a B.A. degree in Education Studies. One thing these courses share is that they are "vocational", which are perceived to be less intellectually rigorous than the traditional academic degrees. Defenders of these courses object that the derogatory comments made in the media rely on the low symbolic capital of new subjects and rarely discuss course contents beyond the titles. Another factor is the correct or incorrect perception that the take up of these subjects, and the decline of more traditional academic subjects like science, engineering, mathematics, is causing annual grade rise in the United Kingdom.
