Detailed Solution

We need to find the number of interior angles more than

180^{0}

in a concave polygon.
We know that a concave polygon will have at least 4 sides.
Concave means a shape that is curved inwards or pointed inwards. When there are dents in it then a polygon is said to be concave.
For example, a star is a concave polygon. Some of the common polygons such as Rectangle, square are convex polygons because no angles in these polygons is more than

180^{0}

.
