Shape Solvers

Solve a triangle from SSS, SAS, ASA, AAS, or SSA inputs and calculate sides, angles, area, perimeter, altitudes, medians, and circle radii.

Calculate right-triangle legs, hypotenuse, acute angles, area, perimeter, altitude to hypotenuse, projections, medians, and circle radii.

Find the hypotenuse, find a missing leg, or check right-triangle side relationships with the Pythagorean theorem.

Calculate cylinder volume, base area, lateral area, total surface area, diameter, height, radius, and axial-section values.

Calculate cone volume, base area, lateral surface area, total surface area, slant height, radius, height, diameter, and net-sector angle.

Calculate sphere radius, diameter, great-circle circumference, surface area, volume, and great-circle area from one known value.

Calculate cube edge length, volume, total surface area, face area, face diagonal, space diagonal, and total edge length.

Calculate rectangular prism volume, surface area, face areas, space diagonal, total edge length, and missing dimensions.

Calculate trapezoid area, perimeter, height, legs, diagonals, and angles from bases and height, an offset, or all four sides.

Calculate parallelogram area, perimeter, height, diagonals, and angles from sides and angle, base and height, area and sides, or diagonals.

Calculate rhombus area, perimeter, side, height, diagonals, angles, inradius, and circumradius-style checks from common input pairs.
