A new computational approach, built on data-driven techniques, is making it possible to turn simple 2D sketch into a realistic 3D shape, with little or no user input necessary. A new computational ...

Find out about regular 2D shapes and irregular polygons. Types of triangle Find out about scalene, equilateral, isosceles and right-angled triangles. Parts of a circle Discover the features of a ...

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 ...
