Geometry calculator

Pick a shape, type its measurements and get its area, perimeter or volume at once, each result with its formula and the numbers substituted.

What you can do

Plane figures: square, rectangle, triangle, equilateral triangle, circle, ellipse, rhombus, parallelogram, trapezoid, regular n-sided polygon, circular sector and annulus.
Solids: cube, cuboid, regular prisms with any number of sides and prisms with any base, cylinder, cone, conical frustum, regular pyramid, sphere, hemisphere, spherical cap, ellipsoid and torus.
Volume, lateral and total area, diagonals, slant heights, apothems and angles.
Start from another value: the side of a square of known area, the radius of a sphere of known volume…
Solve triangles from three values (SSS, SAS, ASA, AAS, SSA or two sides and the area): sides, angles, area, perimeter, heights, medians, inradius and circumradius and the type of triangle, with a drawing to scale and both triangles of the ambiguous case.
