## Description

The **Pythagorean Theorem Calculator** is a free, user-friendly Chrome extension designed to compute any diagonal or side length of squares, rectangles, and right triangles. By simply inputting two known side values and clicking the calculate button, users instantly receive the third side's measurement based on the Pythagorean theorem.

Ideal for students and professionals in mathematics and science, this tool leverages the fundamental relation in Euclidean geometry stating that the square of the hypotenuse equals the sum of the squares of the other two sides of a right triangle. Whether you're solving geometry homework or conducting scientific calculations, this extension offers quick and accurate results.
