Geometry Calculator

Geometry Calculator helps you calculate angles, lengths, areas, volumes and centers of gravity for common 2D and 3D shapes. Clear diagrams, simple parameter entry and easy-to-read results make it a practical tool for learning, exam preparation, engineering calculations and everyday use. The app includes nearly 50 geometry calculators across seven categories: triangles, circles and ellipses, polygons, cubes, pyramids and truncated pyramids, spheres and ellipsoids, and cylinders, cones and tori. Each calculator provides a diagram and clearly labeled parameters to help you enter the known values and find the results you need. For supported shapes, multiple input methods let you work with different combinations of known measurements. For example, a triangle can be defined by three sides, two sides and the included angle, or two angles and the included side. Choose the method that matches your problem and calculate directly, without first rearranging formulas by hand.
