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 ...

This KS2 maths article explains how to sort 2D and 3D shapes according to their properties using Carroll diagrams and Venn diagrams, ...

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 ...

An AI method enables the generation of sharp, high-quality 3D shapes that are closer to the quality of the best 2D image models. Previous approaches typically generated blurry or cartoonish 3D shapes.

Researchers have developed a technique that programs 2D materials to transform into complex 3D shapes.
