Two-Dimensional (2D) Geometry
Planar geometry engines covering polygons, triangle trigonometry, quadrilateral properties, and smooth conic curves. Each calculator provides closed-form radical representations and interactive coordinate geometry blueprints.
Polygons & Shapes
Regular and equilateral polygons. Calculate area, perimeter, apothem, circumradius, and diagonal vectors.
Triangle Trigonometry
Right triangles, Heron's formula, Law of Sines, Law of Cosines, incenter, circumcenter, and centroid computations.
Quadrilaterals & Parallelograms
Squares, rectangles, parallelograms, rhombuses, trapezoids, and cyclic quadrilaterals (Brahmagupta's formula).
Circles & Conic Curves
Circle sectors, circular segments, annulus rings, ellipses, parabolas, and chord length calculations.
