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:

• \( c \) — Hypotenuse (side opposite the right angle)
• \( a \) and \( b \) — Other two sides

Explanation: Enter any two sides to calculate the third side. All values must be > 0.

3. Importance of Right Triangle Calculations

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

4. Using the Calculator

Tips: Enter any two known sides (leave the third field empty) and click Calculate to find the missing side.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: The calculator works with any consistent units (meters, feet, inches, etc.).

Q2: Can I calculate angles with this?
A: No, this calculator only finds side lengths. For angles, use trigonometry functions.

Q3: What if I get an error?
A: Ensure you've entered exactly two sides and that the hypotenuse is the longest side.

Q4: How accurate are the results?
A: Results are accurate to 3 decimal places for precise measurements.

Q5: Can this be used for non-right triangles?
A: No, use the Law of Cosines for other triangle types.
