Geometry & Math

These tools turn shape math into something you can drag, count, and compare. Instead of a static formula page, you get a living diagram that updates as inputs change.

Start with Shape Lab for 2D shapes, Solid Lab for 3D volume, or Plot Lab for interactive coordinate geometry, angles, trig, and the golden spiral. More utilities are on the way.

Best use cases

• Checking area and perimeter while resizing a shape by hand.
• Teaching coordinate geometry, irregular polygons, and unit-circle trig.
• Seeing why a² + b² equals c² with squares on each side.
• Exploring volume, surface area, and tank fill on morphing 3D solids.
