1. What is a Right Triangle Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( a \) and \( b \) — Legs of the right triangle
• \( c \) — Hypotenuse (side opposite the right angle)

Explanation: Enter any two sides to calculate the third. The calculator automatically determines which side to compute.

3. Importance of Right Triangle Calculations

Details: Right triangle calculations are fundamental in geometry, construction, navigation, and many engineering applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What if I know two sides but not which is the hypotenuse?
A: The calculator automatically identifies the longest side as the hypotenuse.

Q2: Can I use this for non-right triangles?
A: No, this calculator only works for right triangles. Use the Law of Cosines for other triangles.

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: How precise are the results?
A: Results are displayed to 3 decimal places for accuracy.

Q5: What if I get an error?
A: Ensure you've entered exactly two sides and that they form a valid triangle (sum of two sides must be greater than the third).
