Algebra & Geometry
Quadratic equation, triangle, circle, Pythagorean and matrix calculators.
Circle Calculator
Area, circumference, diameter — and 90° arc & sector — from radius.
Triangle Calculator
Area (Heron's), perimeter and angles from three sides.
Pythagorean Theorem Calculator
a² + b² = c² — solve for any side of a right triangle.
Quadratic Equation Solver
Solve ax² + bx + c = 0 — real and complex roots, with discriminant.
Matrix Calculator
Add, subtract, multiply and find determinants of 2×2 and 3×3 matrices.
Algebra and Geometry Calculators
Algebra and geometry calculators solve equations, compute areas and volumes, and verify geometric relationships. They are essential tools for students, teachers, and engineers.
Each calculator shows the solution process, helping you understand how the answer was derived. This makes them useful for learning and verifying work, not just getting answers.
These tools handle common algebraic and geometric problems found in high school and college courses, from quadratic equations to triangle properties.
