Enter the known sides or angles into the calculator to determine the missing side of the right triangle.

## Right Triangle Calculation Formula

The following formulas are used to calculate the sides of a right triangle:

c = √(a² + b²) a = √(c² - b²) b = √(c² - a²)

Variables:

- a is one of the legs of the triangle
- b is the other leg of the triangle
- c is the hypotenuse of the triangle

To calculate the missing side, use one of the formulas above depending on which sides you already know.

## What is Right Triangle Calculation?

Right triangle calculation involves finding the lengths of the sides or the measure of the angles of a right triangle using the Pythagorean theorem or trigonometric ratios. Knowing the properties of right triangles is essential in various fields including engineering, physics, and architecture.

## How to Calculate a Missing Side of a Right Triangle?

The following steps outline how to calculate the missing side of a right triangle:

- First, determine which sides or angles you already know.
- Next, choose the appropriate formula based on the known values.
- Use the formula from above: c = √(a² + b²) or a = √(c² – b²) or b = √(c² – a²).
- Finally, calculate the missing side by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Side A = 3

Side B = 4

Calculate the hypotenuse:

c = √(3² + 4²) = √(9 + 16) = √25 = 5

## FAQ

**1. What is the hypotenuse?**

The hypotenuse is the longest side of a right triangle, opposite the right angle.

**2. How do I use the right triangle calculator?**

Simply enter the known side lengths or angles into the calculator fields and click “Calculate” to find the missing side.

**3. Can this calculator be used for non-right triangles?**

No, this calculator is specifically designed for right triangles. For non-right triangles, other methods such as the Law of Sines or the Law of Cosines are used.

**4. How accurate is this calculator?**

The calculator provides a precise calculation based on the inputs provided. For exact figures, ensure that measurements are accurate.

**5. Can I calculate angles using this calculator?**

Yes, you can calculate angles using trigonometric ratios if at least one angle and one side are known.
