**Introduction**

Are you in need of a simple yet effective tool to calculate parallelogram angles? Look no further! In this guide, we will walk you through the process of creating an HTML code for a Parallelogram Angle Calculator. Whether you have a known angle and want to find another, or you simply want to perform quick angle calculations, this tool will make your task a breeze. Below, we will cover how to use the calculator, the formula behind it, provide an example, address some frequently asked questions, and conclude with a summary.

## How to Use

Using the Parallelogram Angle Calculator is straightforward. Follow these steps:

**Input Known Angle (degrees):**Enter the value of the angle you already know in degrees. This is the angle you have in your parallelogram.**Input Angle to Find (degrees):**Enter the angle you want to find in degrees. This is the angle you wish to calculate.**Use Formula (A = 180 – B):**The calculator employs the formula A = 180 – B to calculate the unknown angle. A represents the angle to find, and B is the known angle.**Click the Calculate Button:**Make sure to include a clickable <button>element within a <form> to trigger the calculation.

## Formula

The formula used for calculating the unknown angle in a parallelogram is as follows:

Where:

**A**is the angle to find (the unknown angle).**B**is the known angle (the angle you already have).

## Example

Let’s say you have a known angle B of 60 degrees in your parallelogram. You want to find the angle A. Using the formula:

So, the angle A in your parallelogram is 120 degrees.
