Geometric Shape Calculator

Geometry Math Calculator is a practical tool app focused on calculations for 2D and 3D shapes. It helps you quickly compute common geometric values such as angles, lengths, areas, volumes, and centroids. With an intuitive interface, simple input, and clear results, it is suitable for studying, exams, engineering calculations, and daily use. The app includes nearly 50 built-in shape examples across 7 major categories: triangles, circles/ellipses, polygons, cubes, pyramids/frustums, spheres/ellipsoids, and cylinders/cones/torus. Each shape comes with a diagram and clear parameter descriptions—just enter the known values to get accurate results. For the same shape, the app supports multiple input methods to match different known conditions in problems and real engineering scenarios. For example, a triangle can be defined using SSS (three sides) or SAS (two sides and the included angle), ASA, and more. No extra derivation is needed—simply input the parameters to complete the calculation.
