1. What is a Right Triangle Calculator?

Definition: This calculator computes the hypotenuse of a right triangle using the Pythagorean theorem.

Purpose: It helps students, engineers, and construction professionals calculate missing side lengths in right-angled triangles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( c \) — Hypotenuse (longest side)
• \( a \) — First leg of the triangle
• \( b \) — Second leg of the triangle

Explanation: The squares of the two shorter sides are added together, and the square root of this sum gives the hypotenuse length.

3. Importance of Right Triangle Calculations

Details: Right triangle calculations are fundamental in geometry, construction, navigation, and various engineering applications.

4. Using the Calculator

Tips: Enter the lengths of both legs (a and b) in meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate a leg if I know the hypotenuse and one leg?
A: Yes, you can rearrange the formula to \( a = \sqrt{c² - b²} \).

Q2: What units should I use?
A: The calculator uses meters, but any consistent unit can be used as long as all sides are in the same unit.

Q3: Does this work for all triangles?
A: No, only for right-angled triangles (one 90° angle).

Q4: How accurate are the results?
A: Results are accurate to 3 decimal places, sufficient for most practical applications.

Q5: What if I get an error?
A: Ensure all inputs are positive numbers and you've entered values for both legs.
