📐 Pythagorean Theorem Calculator – Simple, Accurate & Educational

The Pythagorean Theorem Calculator is a powerful and easy-to-use online tool designed to help you calculate the hypotenuse, area, and perimeter of a right-angled triangle quickly and accurately. Whether you are a student, teacher, engineer, architect, or math enthusiast, this calculator makes solving right triangle problems effortless.

The Pythagorean Theorem is one of the most fundamental principles in mathematics. It states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Mathematically, this is written as:

c = √(a² + b²)

Using this calculator, you only need to enter the values of Side A and Side B. The tool instantly calculates the hypotenuse (c), along with the area and perimeter, and clearly displays the formulas used for each result. This makes it not only a calculator but also an excellent learning tool.

✨ Key Features of This Calculator

✔ Calculates Hypotenuse (c) using the Pythagorean Theorem
✔ Computes Triangle Area using the formula A = (a × b) ÷ 2
✔ Finds Triangle Perimeter using P = a + b + c
✔ Supports multiple measurement units (mm, cm, m)
✔ Displays formulas alongside results for better understanding
✔ Clean, modern, and student-friendly interface

This calculator is especially useful for school homework, exams, competitive tests, engineering calculations, construction planning, and geometry practice. By showing the formulas next to the calculated values, it helps users understand how the answer is derived, not just what the answer is.

🎓 Who Can Use This Tool?

Students learning geometry or trigonometry
Teachers explaining right-angled triangles
