1. What is a 90 Degree Angle Triangle Calculator?

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

Purpose: It helps students, engineers, and construction professionals quickly determine the longest side of a right triangle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( c \) — Hypotenuse (longest side)
• \( a \) — First leg of the triangle
• \( b \) — Second leg of the triangle

Explanation: The sum of the squares of the two legs equals the square of the hypotenuse in a right triangle.

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 the lengths of both legs (must be positive numbers). The calculator will compute the hypotenuse.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Any consistent units (meters, feet, inches) can be used as long as both legs are in the same units.

Q2: Does this work for non-right triangles?
A: No, this calculator only works for triangles with a 90-degree angle.

Q3: What if I know the hypotenuse and one leg?
A: Rearrange the formula: \( a = \sqrt{c^2 - b^2} \) to find the missing leg.

Q4: How accurate are the results?
A: Results are mathematically precise, though practical measurements may have some error.

Q5: Can I use this for 3D calculations?
A: The Pythagorean theorem can be extended to 3D: \( d = \sqrt{a^2 + b^2 + c^2} \).
