Level 3 Hub • Planar Euclidean Geometry
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.
Active Solvers
Polygons & Shapes
Regular and equilateral polygons. Calculate area, perimeter, apothem, circumradius, and diagonal vectors.
Active Solvers
Triangle Trigonometry
Right triangles, Pythagorean theorem, altitude to hypotenuse, inradius, and circumradius computations.
Applied Geometry
Structural & Roof Geometry
Roof pitch ratios, slope grades, miter plumb cuts, birdsmouth seat cuts, and rafter length formulas.
Active Solvers
Circles & Conic Curves
Circle sectors, circular segments, arc length, chord length, and sagitta height inversions.
