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.S Big Grin

on'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.

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.

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
