Discover angles, shapes, proofs, and spatial relationships through interactive 3D models and dynamic geometric constructions. From Euclidean axioms to fractal patterns.
Geometry is the mathematical study of shapes, sizes, positions, and properties of space. It uses axioms, theorems, and logical deductions to explore relationships between geometric objects.
Construct geometric proofs with step-by-step validation. Use drag-and-drop elements to form logical arguments and visualize consequences.
Start Proof Exercises →Transform shapes with sliders for angles, lengths, and symmetry. Observe real-time effects on geometric properties and relationships.
Explore Constructions →Explore the five postulates that define classical geometry. Modify axioms to see non-Euclidean geometries emerge.
Visualize translations, rotations, and dilations in 2D/3D space. Understand symmetry groups and invariance.
Create and analyze complex fractals. Discover self-similar patterns across different scales in nature.
200+ interactive constructions, 150+ geometric proofs, and 3D visualizations to master geometry concepts at your pace.
