Pythagorean Theorem Calculator Using JavaScript

Demo👀

How do you make a Pythagorean Theorem Calculator Using JavaScript!

1st Step:-

First you open your HTML Editor like - Notepad++,Subline Text,Brackets, etc.

Then start program use Html, Css, Javascript.

2nd Step:-

Copy the html code and then Paste your HTML Editor into <body> here </body> section.

HTML Code :-

<div id="lcol">

  <div id="doc">
  <!-- #BeginEditable "doctext" -->
  <h1>
Pythagorean theorem calculator</h1>
<form name="calcform" autocomplete="off">
  <p>
Hypotenuse (c) calculation:</p>
<table class="calc2">
    <tbody>
<tr>
      <td>Enter leg (a):</td>
      <td><input type="number" name="a1" min="0" step="any" oninput="calc_c()" autofocus></td>
    </tr>
<tr>
      <td>Enter leg (b):</td>
      <td><input type="number" name="b1" min="0" step="any" oninput="calc_c()"></td>
    </tr>
<tr>
      <td>Hypotenuse (c) result:</td>
      <td><input type="number" step="any" name="c1" class="outtext" readonly></td>
    </tr>
</tbody>
  </table>
<p>
Leg (a) calculation:</p>
<table class="calc2">
    <tbody>
<tr>
      <td>Enter leg (b):</td>
      <td><input type="number" name="b2" id="b2" min="0" step="any" oninput="calc_lega()"></td>
    </tr>
<tr>
      <td>Enter Hypotenuse (c):</td>
      <td><input type="number" name="c2" id="c2" min="0" step="any" oninput="calc_lega()"></td>
    </tr>
<tr>
      <td>Leg (a) result:</td>
      <td><input type="number" step="any" name="a2" class="outtext" readonly></td>
    </tr>
</tbody>
  </table>
<p>
Leg (b) calculation:</p>
<table class="calc2">
    <tbody>
<tr>
      <td>Enter leg (a):</td>
      <td><input type="number" name="a3" id="a3" min="0" step="any" oninput="calc_legb()"></td>
    </tr>
<tr>
      <td>Enter hypotenuse (c):</td>
      <td><input type="number" name="c3" id="c3" min="0" step="any" oninput="calc_legb()"></td>
    </tr>
<tr>
      <td>Leg (b) result:</td>
      <td><input type="number" step="any" name="b3" class="outtext" readonly></td>
    </tr>
</tbody>
  </table>
</form>
</div>
</div>

3rd Step:-

Copy the css code and then Paste your HTML Editor into <head> here </head> section.

CSS Code :-
