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.
a convex polygon
No, any polygon.

It is a convex polygon.
A convex polygon
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 convex polygon
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.
