2D shapes have sides and corners (also called vertices). Here are some 2D shapes you might know. Why not see how much you know about this topic already? Then work through the page and see if you ...

Horváth soon devised an algorithm that could warp polygonal tilings of the plane into tilings of shapes with just two vertices. Using it, the team devised rounded, soft, two-vertex tiles from ...

24 permutations of (1,2,3,4), which are the vertices of the 4-permutahedron, a 3D polytope that lives in 4-space. This polytope is actually a truncated octahedron, a shape with 14 sides (six ...
