A convex polygon does not.

What is the difference between a convex shape and a concave shape?

i dont think any1 knows * * * * * A concave polygon has at least one reflex angle. Equivalently, in a convex polygon, a line joining ANY two points in (or on) the polygon lie wholly within (or on) the polygon. In a concave polygon there are at least two points for which the line joining them does not lie wholly inside (or on) the polygon.

What are the similarities between regular polygon and a concave polygon?

A regular polygon is a special kind of convex polygon - one in which all the sides are of the same length and all the angles are equal. Convex and concave polygons form disjoint sets: so no concave polygon can be regular.

A pool is in the shape of a polygon. The segments and vertices of the polygon are shown. Is this polygon convex or concave?


What the difference between convex and non convex polygons?

In a non-convex (or concave) polygon, at least one interior angle is a reflex angle. An alternative definition is that if you take any two points inside a conves polygon, the line joining them is wholly inside the polygon.

What is a definition for non convex polygon?

A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
