Node Pythagorean

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

Installation

This is a Node.js module available through the npm registry.

Before installing nodepythagorean, download and install Node.js

Installation is accomplished using the npm install command:

$ npm i nodepythagorean --save

Usage

Node Pythagorean is a very simple package to use.

Finding The Hypotenuse

In this problem we are solving for the hypotenuse, so we use the findHypotenuse function that takes in two side lengths (6 and 8).

This function returns a number which you can assign a variable name to.

var nodepythagorean = require("nodepythagorean");

var x = nodepythagorean.findHypotenuse(6, 8));

console.log(x);

// 10

Finding A Missing Side

In this problem we are solving for x, the missing side length, so we use the findSide function that takes in a known side length, and the hypotenuse. The hypotenuse should be passed into the function first.

This function also returns a number which you can assign a variable name to.

var nodepythagorean = require("nodepythagorean");

var x = nodepythagorean.findSide(10, 8);

console.log(x);

// 6
