Mighty Geometry Helper v1.0

[uber1337]

Its called the Geometry "Helper" because I couldn't figure out how to find the orthocenter of a triangle using python. It solves everything up to the algebra part, that's where the human comes in. This is kinda experimental because I haven't tested everything out but so far it has 5 features.

Notes:

• Finds the slope of a line
  
• Can tell if a line is perpendicular or parallel to another
  
• Finds the orthocenter of a triangle(kinda)
  
• Can tell if a triangle is a right triangle
  
• Finds the midpoint of a line
  
• If you find bugs please tell me
  
• If you know how to use algebra in python please tell me
  
• It is a little sloppy, just thought that today's challenge would lead to the ease of tomorrow's geometry homework
  

Please help me with the bugs I have already found

Known Bugs:

• When finding the slope sometimes it will spit out a zero instead of a fraction or a decimal
  
• Has error's in finding slope when zero's are involved(It says "Cannot divide by 0" even when I solve it without having to divide by 0)
  

If you have any suggestions for the next version, please tell me
P.Son't run this in the IDLE unless you want a black window popping up every two seconds

Looks good, only think I would change is use float instead of int.
I was working on something similar, you beat me to it, so here what I had(This isnt finished, but no use in finishing it now )

What exactly does that change? Will using float make the output a decimal instead of a rounded answer? And for some things I can't use float,
Ex. For perpendicular lines I need int for the .denominator and .numerator attributes which float doesn't have.

[nevets04]

float will give more exact answers when dividing. Look:

Code:

>>> x = float(2)
>>> y = float(3)
>>> x/y
0.66666666666666663
>>> x = int(2)
>>> y = int(3)
>>> x/y
0
