3D Geometry is a app designed for observing and manipulating geometrical figures in three dimensional space.
There are many types of three-dimensional shapes. You've surely seen spheres and cubes before. In this app, you'll learn about polyhedra — three-dimensional shapes whose faces are polygons — and you'll also learn about three special types of polyhedra: prisms, pyramids and platonics.
