1. What is a Right Triangle Side Calculator?

Definition: This calculator computes the length of one side of a right triangle when you know the other side and the hypotenuse.

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

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( a \) — The calculated side (meters)
• \( b \) — The known side (meters)
• \( c \) — The hypotenuse (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: Accurate side calculations are essential in construction, engineering, navigation, and various STEM applications.

4. Using the Calculator

Tips: Enter the known side length and hypotenuse in meters. Both values must be positive, and hypotenuse must be greater than the known side.

5. Frequently Asked Questions (FAQ)

Q1: What if I know sides a and b but need hypotenuse?
A: Use the formula \( c = \sqrt{a^2 + b^2} \). We may add this functionality in a future version.

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

Q3: Why does hypotenuse need to be larger than side b?
A: In a right triangle, the hypotenuse is always the longest side.

Q4: Can I use this for non-right triangles?
A: No, this calculator only works for right-angled triangles. For other triangles, use the Law of Cosines.

Q5: How precise are the results?
A: Results are precise to 3 decimal places, suitable for most practical applications.
