1. What is the Hypotenuse Formula?

The hypotenuse formula, also known as the Pythagorean theorem, calculates the length of the hypotenuse of a right triangle from the lengths of the other two sides. It states that in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( H \) — Length of the hypotenuse
• \( a \) — Length of one leg of the right triangle
• \( b \) — Length of the other leg of the right triangle

Explanation: The formula calculates the square root of the sum of the squares of the two legs to find the hypotenuse length.

3. Importance of Hypotenuse Calculation

Details: Calculating the hypotenuse is fundamental in geometry, trigonometry, and various practical applications such as construction, navigation, and physics. It helps determine distances and relationships in right-angled configurations.

4. Using the Calculator

Tips: Enter the lengths of both legs (a and b) in the same units. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Can this formula be used for any triangle?
A: No, the Pythagorean theorem applies only to right triangles where one angle is exactly 90 degrees.

Q2: What units should I use for the measurements?
A: You can use any units (cm, m, inches, etc.) as long as both legs are measured in the same units. The result will be in those same units.

Q3: What if I know the hypotenuse and one leg?
A: You can rearrange the formula to solve for the unknown leg: \( a = \sqrt{H^2 - b^2} \) or \( b = \sqrt{H^2 - a^2} \).

Q4: Does the formula work for 3D space?
A: For 3D space, the formula extends to: \( H = \sqrt{a^2 + b^2 + c^2} \) for the space diagonal of a rectangular prism.

Q5: What are some practical applications of this formula?
A: It's used in construction for ensuring right angles, in navigation for calculating shortest distances, and in various engineering and physics calculations.
