  3. May 7, 2024 · 1. Regular Polygon. A regular (or simple) polygon is a shape with equal angles and multiple sides with equal lengths. Regular polygons can also be categorized as convex polygons because the equal sides canter inward where they connect, creating several v-shaped vertices. 2. Irregular Polygon.

    May 20, 2024 · Specifically, a k-simplex is a k-dimensional polytope that is the convex hull of its k + 1 vertices. More formally, suppose the k + 1 points , …, are affinely independent, which means that the k vectors , …, are linearly independent. Then, the simplex determined by them is the set of points

    3 days ago · Convex geometry investigates convex shapes in the Euclidean space and its more abstract analogues, often using techniques of real analysis and discrete mathematics. It has close connections to convex analysis , optimization and functional analysis and important applications in number theory .

  6. May 7, 2024 · If none of the sides, when extended, intersects the polygon, it is a convex polygon. Otherwise, it is concave. A polygon with all sides equal is equilateral; an example is a rhombus, which is an equilateral quadrilateral. A polygon with all interior angles equal is equiangular; an example is a rectangle, which is an equiangular quadrilateral.
