Geometry Calculator Plus

Geometry Calculator — the ultimate shape solver for students, engineers, architects, and anyone who works with measurements. Instantly calculate area, perimeter, volume, surface area, angles, diagonals, and dozens of other properties for 15 shapes — all in one beautifully designed app. Just enter what you know, and every result updates in real time. 15 Shapes. Every Property. • 2D Shapes - Circle, Rectangle, Square, Triangle, Parallelogram, Trapezoid, Regular Polygon, Ellipse — with full outputs including circumradius, inradius, diagonals, apothem, eccentricity, and more. • 3D Shapes - Cube, Cuboid, Sphere, Cylinder, Cone, Square Pyramid, Triangular Prism — with volume, surface area, lateral area, slant height, face areas, and space diagonals. Advanced Triangle Solver Solve any triangle from any combination of known values: • SSS - three sides • SAS - two sides and included angle • ASA - two angles and included side • AAS - two angles and non-included side • SSA - automatically detects and presents both solutions in the ambiguous case Outputs include all sides, all angles, area, perimeter, circumradius, and inradius. Live Shape Visualization Every shape is drawn in real time as you type. Pan and pinch to zoom on 2D shapes. Rotate and inspect 3D shapes freely with full camera control. Labels update dynamically to reflect your exact values.
