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.

Is triangle is a convex or nonconvex?
A triangle is normally nonconvex on a flat surface
Explain how to tell whether a polygon is a convex?
If, for any two points A and B in the polygon, all points with position A + kB are inside the polygon for 0 ≤ k ≤ 1, then the polygon is convex. In simple terms, if all points on the line AB lie inside the polygon, it is convex. If there is at least one point on AB that is outside the polygon then it is not a convex polygon.
How can you tell whether a polygon is a convex?
A polygon (or any other plane shape) is convex if you take any two points inside it (or on its boundary) then the line joining those points is wholly inside (or on the boundary of) the polygon.
Is the following polygon convex or concave?
is this a polygon? is it concaver or convex
What is the difference between a concave polygon and 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.
