1. What is a Right Triangle Calculator?

Definition: This calculator solves for missing sides in a right-angled triangle using the Pythagorean theorem.

Purpose: It helps calculate unknown lengths in right triangles, commonly used in construction, engineering, and geometry.

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. The calculator automatically determines which side is missing.

3. Importance of Right Triangle Calculations

Details: Right triangle calculations are fundamental in construction for roof pitches, stair stringers, framing, and land surveying.

4. Using the Calculator

Tips: Enter any two known sides (leave the unknown side as 0). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if I know all three sides?
A: The calculator will verify if they satisfy the Pythagorean theorem (a² + b² = c²).

Q2: Can this calculate angles?
A: No, this version only calculates side lengths. Use our Trigonometry Calculator for angle calculations.

Q3: What units should I use?
A: The calculator works with any consistent units (meters, feet, etc.) as long as all sides use the same unit.

Q4: What if I get an imaginary number result?
A: This means the sides you entered cannot form a right triangle. Check your measurements.

Q5: How accurate are the results?
A: Results are accurate to 3 decimal places, sufficient for most construction applications.
