Mighty Geometry Helper v1.0 - uber1337 - 12-05-2009
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
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

Ex. For perpendicular lines I need int for the .denominator and .numerator attributes which float doesn't have.
RE: Mighty Geometry Helper v1.0 - nevets04 - 12-05-2009
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
