title: How do I find the circumcenter of the triangle using python without external libraries?
body: <p>I am trying to find the circumcenter of a triangle with python and no external libraries for a geometry calculator that I am making. The thing is I can't use equations such as y=mx+b because the computer thinks that I am trying to define a variable rather than doing algebra.</p>
  
  <p>I have tried a lot of different things such as using sympy and shapely and none of them worked. So far I can find the midpoint and the slope. I am not really sure what to do. Please help. Thank you!</p>
  
  <pre class="lang-py prettyprint-override"><code>def circumcenter():
      c1 = float(input('What is x of point 1?'))
      c2 = float(input('What is y of point 1?'))
      c3 = float(input('What is x of point 2?'))
      c4 = float(input('What is y of point 2?'))
      c5 = float(input('What is x of point 3?'))
      c6 = float(input('What is y of point 3?'))
      m1 = c1 + c3
      m2 = c2 + c4
      m3 = m1 / 2
      m4 = m2 / 2
      s1a = c3 - c1
      s1b = c4 - c2
      s1c = s1a / s1b
      s2a = c5 - c3
      s2b = c6 - c4
      s2c = s2a / s2b
      s1 = -1 / s1c
      s2 = -1 / s2c
  </code></pre>
  
  <p>There is no output yet because if I print something it will not mean anything other than the slope.</p>
