Hypotenuse Calculator

A right triangle is one of the most fundamental shapes in geometry, and calculating its properties is a common task in math, physics, and engineering. The hypotenuse is the longest side of a right triangle, opposite the right angle, and it is essential for solving triangle-related problems.

Our Hypotenuse Calculator makes it easy to calculate not just the hypotenuse, but also the two angles, perimeter, and area of any right triangle. This tool is perfect for students, teachers, engineers, and anyone working with geometry.

How to Use the Hypotenuse Calculator

Using the calculator is straightforward and user-friendly:

  1. Enter the Two Sides:
    Provide the lengths of Side A (adjacent) and Side B (opposite) of the triangle in the input fields. Ensure both values are positive numbers.
  2. Click Calculate:
    Press the Calculate button. The calculator will instantly display:
    • Hypotenuse (c) – the longest side of the triangle
    • Angle α – angle opposite side B
    • Angle β – angle opposite side A
    • Perimeter – sum of all three sides
    • Area – area of the triangle
    • Formula reference – reminder that c2=a2+b2c^2 = a^2 + b^2c2=a2+b2
  3. Reset for New Calculations:
    Click the Reset button to clear the fields and calculate a new triangle.

  • Accurate Results: Avoid manual errors in trigonometric calculations.
  • User-Friendly: Simple interface ideal for students, teachers, and professionals.
  • Versatile: Works with integer or decimal side lengths.
  • Educational Value: Helps understand the Pythagorean theorem and triangle properties.

This calculator is particularly useful for geometry homework, engineering design, architectural plans, and any scenario involving right triangles.

Understanding the Hypotenuse and Triangle Properties

The hypotenuse is determined using the Pythagorean theorem:c2=a2+b2c^2 = a^2 + b^2c2=a2+b2

Where:

  • c is the hypotenuse
  • a and b are the other two sides

Other properties calculated by this tool include:

  1. Angles: Using trigonometry, the angles are computed as:
    • α=arctan⁡(ba)\alpha = \arctan\left(\frac{b}{a}\right)α=arctan(ab​)
    • β=90°−α\beta = 90° - \alphaβ=90°−α
  2. Perimeter: Sum of all three sides: P=a+b+cP = a + b + cP=a+b+c
  3. Area: Area of a right triangle: A=a×b2A = \frac{a \times b}{2}A=2a×b​

By providing all these details, the calculator helps users visualize and understand the triangle fully.
