Geometry Calculators

Easily find the length of any side of a right triangle using the Pythagorean theorem (a² + b² = c²).

Solve any triangle's missing sides, angles, area, and perimeter based on the information you provide.

Calculate a circle's area, circumference, or diameter based on any known measurement.

Calculate the area of an annulus (a ring-like shape) by providing the outer and inner radii.

Perform 2D geometric transformations including translation, rotation, and scaling on points. Ideal for students, designers, and developers working with graphics.
