Geometry & Trigonometry Calculators
Area, volume, triangles and vectors.
Compute area, volume and surface area for common shapes, solve triangles with the laws of sines and cosines, and work with slopes, distances and vectors.
Area CalculatorCompute the area of a square, rectangle, triangle, circle, trapezoid, parallelogram or ellipse.Circle CalculatorFind the area, circumference and diameter of a circle from its radius.Distance CalculatorFind the straight-line distance between two points in the coordinate plane.Pythagorean Theorem CalculatorFind the missing side of a right triangle. Enter any two of the two legs and the hypotenuse.Regular Polygon CalculatorFind the area, perimeter, interior and exterior angles, apothem and circumradius of a regular polygon.Right Triangle CalculatorSolve a right triangle: enter any two of the two legs and the hypotenuse to find the rest.Slope CalculatorFind the slope, y-intercept and incline angle of the line through two points.Surface Area CalculatorCompute the total surface area of a cube, box, sphere, cylinder or cone.Triangle CalculatorSolve a triangle from three sides, or from two sides and the angle between them.Trigonometry Solver CalculatorSolve a triangle from SSS, SAS, ASA or AAS using the laws of sines and cosines.Vector CalculatorCompute the magnitudes, dot product, cross product and angle between two 3D vectors.Volume CalculatorCompute the volume of a cube, box, sphere, cylinder, cone or pyramid.
