What is the definition of inflection point in math?
That's a point where the curve of a graph changes from "concave upward" to "concave downward", or vice versa.
Is a concave polygon is regular?
By definition a regular polygon cannot be concave. Concave polygons contain one or more interior angles that are greater than 180 degrees, and regular polygons can never have an interior degree greater than 180 degrees.
What is a definition for non convex polygon?
A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
What is the opposite of Convex?
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
Is a circle concave or convex?
This depends on your definition. One could say that circles ({p in R^n : d(p,m) = r}) are concave, while (open) disks ({p in R^n : d(p,m) < r}) are convex.
Can a regular octagon be concave?
No, a regular octagon cannot be concave. By definition, a regular octagon has all sides and angles equal, and it is a convex polygon, meaning that all its interior angles are less than 180 degrees. A concave polygon, on the other hand, has at least one interior angle greater than 180 degrees, which is not possible in a regular octagon.
What is the mathamatical definition of concave and convex polyhedra?
There is a good way to know if a polyhedra is convex. If you place the shape inside a sphere and all of the vertexes were touching the edge of the sphere, then it would be convex. If all of the vertexes didn't touch the edge, then it would be concave. How simply is that?

Is an arrow concave or convex?
