Discover the Power of the Pythagorean Theorem for Calculating Length

The Pythagorean Theorem is a fundamental concept in mathematics that can be used to find the length of the sides of a right triangle. It's an essential tool for students, engineers, and anyone who needs to work with right triangles. Understanding this theorem is crucial to solving math problems and deriving important formulas in geometry and trigonometry. In this article, we'll explore the Pythagorean Theorem and how it can be used to find the length of a side in a right triangle.

What Is the Pythagorean Theorem?

The Pythagorean Theorem states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the hypotenuse, which is the longest side of the triangle:

a² + b² = c²

where a and b are the lengths of the two shorter sides, and c is the length of the hypotenuse. This theorem is named after Pythagoras, a Greek mathematician who lived in the 6th century BC.

How to Use the Pythagorean Theorem to Find the Length of a Side

Let's say we have a right triangle with a length of 6 units on one side and a length of 8 units on the other side. We want to find the length of the hypotenuse.

We start by plugging in the lengths of the two shorter sides into the Pythagorean Theorem equation:

a² + b² = c²

6² + 8² = c²

36 + 64 = c²

100 = c²

To find the length of the hypotenuse, we take the square root of both sides:

c = √100

Therefore, the length of the hypotenuse is 10 units.
