Introduction

In the world of mathematics, right triangles are a fundamental concept that has been studied for centuries. A right triangle is a triangle with one angle that measures 90 degrees, and it is characterized by the presence of a hypotenuse, which is the longest side of the triangle. In this article, we will explore the Pythagorean theorem, a powerful tool for solving right triangles, and use it to find the value of the hypotenuse in a given right triangle.

The Pythagorean Theorem

The Pythagorean theorem is a mathematical formula that describes the relationship between the lengths of the legs and the hypotenuse of a right triangle. The theorem states that:

a^2 + b^2 = c^2

where a and b are the lengths of the legs of the right triangle, and c is the length of the hypotenuse.

Understanding the Theorem

To understand the Pythagorean theorem, let's break it down into its components. The theorem states that the sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse. This means that if we know the lengths of the legs of a right triangle, we can use the theorem to find the length of the hypotenuse.

Applying the Theorem

Now that we have a good understanding of the Pythagorean theorem, let's apply it to a real-world problem. Suppose we have a right triangle with legs of length a = 14 units and b = 48 units. We want to find the length of the hypotenuse, c.

Using the Pythagorean theorem, we can plug in the values of a and b into the equation:

14^2 + 48^2 = c^2

Expanding the equation, we get:

196 + 2304 = c^2

Combining the terms, we get:

2500 = c^2

Taking the square root of both sides, we get:

c = √2500

Simplifying the expression, we get:

c = 50

Therefore, the length of the hypotenuse of the right triangle is 50 units.

Conclusion

In this article, we have explored the Pythagorean theorem, a powerful tool for solving right triangles. We have used the theorem to find the length of the hypotenuse of a right triangle with legs of length a = 14 units and b = 48 units. The theorem states that the sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse. By applying the theorem to a real-world problem, we have shown how it can be used to find the length of the hypotenuse of a right triangle.
