1. What is a Right Triangle Side Calculator?

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

Purpose: It helps students, engineers, and construction professionals quickly solve right triangle problems using the Pythagorean theorem.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem formula:

Where:

• \( a \) — Missing side length (meters)
• \( b \) — Known side length (meters)
• \( c \) — Hypotenuse length (meters)

Explanation: The square of the hypotenuse minus the square of the known side equals the square of the missing side.

3. Importance of Right Triangle Calculations

Details: Accurate right triangle calculations are essential in construction, navigation, engineering, and various STEM fields.

4. Using the Calculator

Tips: Enter the hypotenuse and one other side length in meters. Both values must be positive numbers, and the hypotenuse must be longer than the other side.

5. Frequently Asked Questions (FAQ)

Q1: What if I know two sides but not the hypotenuse?
A: Use the standard Pythagorean formula: \( c = \sqrt{a^2 + b^2} \).

Q2: What units should I use?
A: The calculator uses meters, but any consistent unit will work as long as all inputs use the same unit.

Q3: What if the hypotenuse is shorter than the other side?
A: The calculator won't return a result as this violates the Pythagorean theorem (hypotenuse must be longest side).

Q4: How precise are the results?
A: Results are calculated to 3 decimal places for most practical applications.

Q5: Can I use this for non-right triangles?
A: No, this calculator only works for right triangles. For other triangles, use the Law of Cosines.
