Result
Instead of solving complex equations manually, this tool instantly provides the correct answer after entering the required values. It supports two important functions:
- Finding the hypotenuse when two sides are known
- Finding a missing side when the hypotenuse and one side are known
The calculator also identifies the triangle type and displays the formula used in the calculation. With fast results, copy/share options, and an easy-to-use layout, it is useful for educational, professional, and everyday purposes.
What Is the Hypotenuse?
In a right triangle, the hypotenuse is the longest side opposite the right angle. It is calculated using the famous Pythagorean theorem:
a2+b2=c2
a
b
c=a2+b2≈21.21
a2+b2=c2≈225.00+225.00=450.00abc
Where:
- a = first side
- b = second side
- c = hypotenuse
This formula is one of the most important concepts in geometry and is widely used in mathematics, engineering, architecture, construction, navigation, and physics.

Practical Example 1 – Finding the Hypotenuse
Suppose a ladder is leaning against a wall.
- Height from ground to wall = 12 feet
- Distance from wall = 5 feet
To find the ladder length:
c=122+52
Result:
- Hypotenuse = 13 feet
This means the ladder must be 13 feet long.
Daily Life Use
This is useful for:
- Ladder positioning
- Roof measurements
- Home construction
- Interior design planning
Practical Example 2 – Finding the Missing Side
Imagine a TV screen has a diagonal length of 50 inches and height of 30 inches. You want to calculate the width.
Formula used:
a=502−302
Result:
- Width ≈ 40 inches
Daily Life Use
This helps in:
- Buying furniture
- TV placement planning
- Room measurement calculations
- DIY projects
