## Pythagorean Theorem Formula

The Pythagorean Theorem is a basic mathematical principle that deals with the lengths of the sides of a right triangle. According to the theorem, the length of the hypotenuse (the side opposite the right angle) squared in a right triangle equates to adding the squares of the lengths of the other two sides. The formula can be written as:

c^2 = a^2 + b^2

In this formula, 'c' indicates the hypotenuse length, while 'a' and 'b' indicate the lengths of the other two sides.

## What is the Pythagorean Theorem?

The Pythagorean Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery. This theorem has far-reaching applications in various fields, including architecture, engineering, and physics. It allows us to determine the unknown side length of a right triangle when the other two sides are known.

## What are Pythagorean Triples?

Pythagorean Triples are sets of three positive integers that satisfy the Pythagorean Theorem. In other words, if you substitute these integers into the formula, the equation holds true. The most famous Pythagorean Triple is (3, 4, 5), where 3^2 + 4^2 = 5^2. Other examples include (5, 12, 13) and (8, 15, 17). Pythagorean Triples have been studied for centuries, and their properties continue to be explored by mathematicians.

## Pythagorean Theorem for Right Triangles

The Pythagorean Theorem specifically applies to right triangles, which are triangles with one angle measuring 90 degrees. The Pythagorean Theorem lets us determine the length of the third side if we know the lengths of two other sides. This is incredibly useful in real-world scenarios, such as calculating distances or determining the size of objects based on measurements.

#### Pythagorean Theorem Rounding Calculator

Dealing with decimal values can sometimes be challenging, especially if you require an answer in whole numbers. Our rounding calculator allows you to round the result to the nearest whole number or any desired decimal place, making it more convenient for practical use.

#### Pythagorean Theorem Calculator Angle

While our calculator primarily focuses on finding side lengths, it's worth mentioning that the Pythagorean Theorem can also help determine angles in a right triangle. You can calculate the angles based on the side lengths by using trigonometric functions such as sine, cosine, and tangent.

#### Pythagorean Theorem Perimeter

The Pythagorean Theorem can also be utilized to find the perimeter of a right triangle. To obtain the perimeter, add up the lengths of all three sides. By substituting the known side lengths into the formula, you can calculate the missing side and then find the perimeter.

#### Find the Length of the Third Side

To find the length of the third side of a right triangle, you can use the Pythagorean Theorem if you already know the length of two sides. Our calculator can help you effortlessly solve this type of geometry problem.

Sometimes, the side lengths obtained from the Pythagorean Theorem may be expressed in radical form, also known as surd form. Radical form signifies that the exact value of the side length cannot be simplified to a whole number or decimal. Our calculator provides results in both radical and decimal forms, allowing you to choose the representation that suits your needs

The Pythagorean Theorem is a powerful mathematical concept that finds practical applications in various fields. With the Pythagorean Theorem Calculator, you can easily solve for the missing side length of a right triangle, whether you're dealing with whole numbers or decimals.

## Pythagorean Theorem Examples

To gain a better understanding of the Pythagorean theorem and its practical applications, let's consider some examples:

###### Example 1:

Given a right triangle with side lengths of 3 and 4, find the hypotenuse length.

Using the Pythagorean theorem, we can solve for the hypotenuse:

c^2 = a^2 + b^2

c^2 = 3^2 + 4^2

c^2 = 9 + 16

c^2 = 25

c = √25

c = 5

Therefore, the length of the hypotenuse is 5 units.

###### Example 2:

Find the area of a right triangle with a hypotenuse of length 10 and one leg measuring 6.

To find the area, we must multiply half the product of the two legs. Using the Pythagorean theorem, we can solve for the missing leg:

c^2 = a^2 + b^2

10^2 = 6^2 + b^2

100 = 36 + b^2

b^2 = 100 - 36

b^2 = 64

b = √64

b = 8

Now that we have the lengths of both legs, we can calculate the area:

Area = (1/2) * a * b

Area = (1/2) * 6 * 8

Area = 24 square units

## FAQ's

### Q. What is the hypotenuse given legs 5 and 9?

A. To determine the hypotenuse of a right triangle with legs measuring 5 and 9, we can utilize the Pythagorean theorem. Applying the theorem, we have: c^2 = a^2 + b^2, where 'c' represents the hypotenuse, and 'a' and 'b' represent the lengths of the legs. Substituting the values, we get c^2 = 5^2 + 9^2 = 25 + 81 = 106. Taking the square root of both sides, we find that the hypotenuse length is approximately √106 ≈ 10.295 units.

### Q. How to do the Pythagorean theorem?

A. To use the Pythagorean theorem, follow these steps: Identify the two shorter sides of the right triangle, often called 'a' and 'b.' Square each of these side lengths by multiplying them by themselves. Add the squares of 'a' and 'b' together. Take the sum's square root to find the hypotenuse length ('c').
