1. What is the Third Side of Right Triangle Calculator?

Definition: This calculator finds the length of the hypotenuse of a right triangle when given the lengths of the other two sides.

Purpose: It helps students, engineers, and construction professionals quickly determine the missing side of a right triangle.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( c \) — Hypotenuse (meters)
• \( a \) — First leg (meters)
• \( b \) — Second leg (meters)

Explanation: The square of the hypotenuse equals the sum of the squares of the other two sides.

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 in meters. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Can I find a leg if I know the hypotenuse and one leg?
A: Yes, you can rearrange the formula: \( a = \sqrt{c^2 - b^2} \).

Q2: Does this work for non-right triangles?
A: No, the Pythagorean theorem only applies to right triangles.

Q3: What units should I use?
A: The calculator uses meters, but you can use any unit as long as all inputs are consistent.

Q4: How precise is the calculation?
A: The result is displayed to 3 decimal places for most practical applications.

Q5: What if I get an error?
A: Ensure both leg values are positive numbers greater than zero.
