A convex polygon is a polygon such that no side extended cuts any other side or vertex; it can be cut by a straight line in at most two points Example: A square is a convex polygon, as is an eqilateral triangle. A star shaped polygon is NOT convex. More generally, In Euclidean space, objects are convex if for every pair of points within the object, every point on the straight line segment that joins them is also within the object.

Is a ploygon convex or not convex?
a polygon is convex
Difference of non convex and convex?
A non convex is a concave and a convex is differently shaped
How do you determine whether a polygon is convex or non-convex?
No interior angle of a convex polygon can exceed 180 degrees. A non-convex polygon has at least one reflex angle (> 180 degrees). Alternatively, a polygon is convex if, given any two points on or inside the polygon, the straight line joining the two points must lie wholly on or inside the polygon. In a non-convex polygon, it is possible to find a pair of points such that the straight line joining them lies outside the polygon for at least some of its length.
