1. What is a 90 Degree Triangle Calculator?

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

Purpose: It helps construction professionals, students, and DIYers calculate triangle dimensions for various projects.

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 values to calculate the third. The calculator will solve for the missing side.

3. Importance of Right Triangle Calculations

Details: Accurate triangle calculations are essential for roof framing, stair construction, land surveying, and many other construction applications.

4. Using the Calculator

Tips: Enter any two known values (two legs, or one leg and hypotenuse) and leave the field you want to calculate empty.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Use any consistent unit (meters, feet, inches) for all sides. The calculator will return results in the same unit.

Q2: Can I calculate a leg if I know the hypotenuse?
A: Yes, enter the hypotenuse and one leg to calculate the other leg.

Q3: What if I get an error message?
A: Ensure you've entered exactly two values and they form a valid right triangle (hypotenuse must be longer than either leg).

Q4: How precise are the results?
A: Results are calculated to high precision and displayed to 3 decimal places.

Q5: Can I use this for non-right triangles?
A: No, this calculator only works for right-angled (90-degree) triangles.
