Two-dimensional (2D) shapes are completely flat. They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they ...

Researchers have developed a technique that programs 2D materials to transform into complex 3D shapes. University of Texas at Arlington researchers have developed a technique that programs 2D ...

How few corners can a shape have and still tile the plane?” mathematician Gábor Domokos asked me over pizza. His deceptively simple question was about the geometry of tilings, also called ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Some examples of solids that incorporate 2D shapes are mentioned in this video by Sanchit — for example ...
