1. What is a Right Angle Triangle Calculator?

Definition: This calculator determines the hypotenuse of a right-angled triangle using Pythagoras' theorem.

Purpose: It helps students, engineers, and construction professionals calculate missing side lengths in right-angled triangles.

2. How Does the Calculator Work?

The calculator uses Pythagoras' theorem:

Where:

• \( c \) — Hypotenuse (longest side, opposite the right angle)
• \( a \) — Length of side adjacent to angle
• \( b \) — Length of side opposite to angle

Explanation: The squares of the two shorter sides are added together, and the square root of this sum gives the hypotenuse length.

3. Importance of Right Angle Triangle Calculations

Details: These calculations are fundamental in construction, navigation, engineering, and various STEM fields where precise measurements are crucial.

4. Using the Calculator

Tips: Enter the lengths of any two sides in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for non-right-angled triangles?
A: No, this calculator only works for right-angled triangles. For other triangles, use the Cosine Rule.

Q2: What units should I use?
A: The calculator uses meters (UK standard), but any consistent unit can be used as long as all inputs are in the same unit.

Q3: How accurate are the results?
A: Results are accurate to three decimal places, sufficient for most practical applications.

Q4: Can I calculate a missing side other than the hypotenuse?
A: This version calculates the hypotenuse. Rearrange the formula to calculate other sides: \( a = \sqrt{c^2 - b^2} \).

Q5: What if I get an error?
A: Ensure all values are positive numbers and you've entered two side lengths.
