A concave polygon informally is one that has a dent.
Concave polygon interior angles. It looks sort of like a vertex has been pushed in towards the inside of the polygon. A polygon with one or more interior angles greater than 180 degrees is referred to as a concave polygon. At least one interior angle is greater than 180 degrees.
More formally a concave polygon has at least one interior angle greater than 180. The pentagon below is concave. A concave polygon is the opposite of a convex polygon.
This polygon is just the opposite of a convex polygon. Every internal angle is less than 180 degrees. A concave polygon is a polygon which is not convex.
The sum of the interior angles of a regular polygon equals 1260 degrees. A concave polygon is a polygon that has one or more interior angles greater than 180 degrees. There is one exterior angle that is not marked.
Some diagonals of a concave polygon lie partly or wholly outside the polygon. A concave polygon is defined as a polygon with one or more interior angles greater than 180. Since the sum of the interior angles in any triangle must add up to 180 degrees no interior angles can be more than 180.
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. How many sides does a polygon have. Given a polygon solve for x and all of the interior angles using sum of interior angles duration.
