Shape Builder 🔷
Build any 2D shape on a grid — drag its corners and see its name, sides, angles, symmetry, perimeter and area worked out, then reflect, rotate, translate or enlarge it. Switch to 3D to turn a solid, unfold its net, see its front, side and plan views, and find its faces, edges, vertices, volume and surface area.
Any polygon, circle or solid
Nets, views & transformations
