1. What is a Right Triangle Calculator?

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

Purpose: It helps construction professionals, students, and DIYers solve for unknown sides in right-angled triangles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Enter any two sides to calculate the third side of a right triangle.

3. Importance of Right Triangle Calculations

Details: Essential for roof framing, stair construction, land surveying, and any project requiring precise right angles.

4. Using the Calculator

Tips: Enter any two known sides (leave one field blank) to calculate the missing side. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What defines a right triangle?
A: A triangle with one 90° angle where the side opposite (hypotenuse) is the longest side.

Q2: Can I calculate angles with this tool?
A: No, this only calculates side lengths. Use our Triangle Angle Calculator for angle calculations.

Q3: What units should I use?
A: The calculator works with any consistent units (meters, feet, etc.) but displays meters by default.

Q4: Why does my calculation show an error?
A: Ensure you've entered exactly two sides and they follow the rule c > a and c > b.

Q5: How accurate are the results?
A: Results are accurate to 3 decimal places for precise measurements.
