No, they do not.
A polygon that has at least one diagonal with points outside the polygon is known as a concave polygon. In a concave polygon, at least one interior angle is greater than 180 degrees, which causes the diagonal connecting two non-adjacent vertices to extend outside the shape. This characteristic differentiates concave polygons from convex polygons, where all diagonals remain inside the figure.
It should be convex
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.

These terms describe polygons. To identify a polygon as convex, we draw a segment from any vertex to any other vertex. This segment cannot go outside of the polygon. Non-convex is concave. If we draw a segment from a vertex to any other vertex, at least one of the segments will go outside of the polygon.
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.

No, any polygon.
A polygon is convex if no two points on it's border define a line segment that falls outside the polygon.
A convex polygon.
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.
