The timeless 2,300-year-old mathematical foundation brought to life with 60FPS reactive vector kinematics, mobile-optimized hitboxes, and interactive proof steppers.
Explore self-contained vector engines built with pure SVG and pointer events. No build toolchains required.
Construct an equilateral triangle on a given finite line segment. Drag endpoints A and B freely in real-time while radial vector offsets keep vertex labels completely unobstructed.
Launch Prop 1 Interactive Demo ↗The crown jewel of Greek mathematics. Drag vertex A along Thales' semicircle to alter triangle proportions with 100% exact right-angle preservation and live area shear equivalence.
Launch Prop 47 Windmill Demo ↗More than just raw propositions. A comprehensive tri-linked learning system uniting classical axioms, real-world engineering, and competitive exam mastery.
27 interconnected Single-Page Applications covering all 465 propositions of the Euclidean canon: Plane Geometry, Eudoxian Proportions, Number Theory, Medial Irrationals, and the 5 Platonic Solids.
