All the interior angles of a convex polygon are less than 180°. At least one interior angle is greater than 180°. The line joining any two vertices of the convex shape lies completely in it. The line joining any two vertices of the concave shape may or may not lie in it.Convex...
If Q n t Q_n^t is either a square of side length n t n^{-t} or an isosceles right triangle with legs of length n t n^{-t} , for n = 1 , 2 , … n=1,2,\\ldots , then the sets Q 1 t , Q 2 t , Q 3 t … Q_1^t, Q_2^t, Q_3^t \\ldots can be ...
Polygons can be classified as convex or concave. In a convex polygon, every diagonal of the figure passes only through interior points of the polygon. In a concave polygon, at least one diagonal of the figure contains points that are exterior to the polygon. Convex polygons are found in ma...

If a 2-dimensional shape is closed and has 3 or more sides, it's called a polygon in geometry. Once a shape is established as a polygon, the next classification is whether it is a convex or concave polygon. What is a convex polygon? A convex polygon is a shape where all the interio...
