[Tutor] triangulation

[Liam Clarke-Hutchinson]

As in Pythagoras?

from math import *

c = sqrt(a^2 + b^2)

Or as in triangulation on a 2D surface, navigation etc.?

from math import *

o = tan(theta) * a
o = sin(theta) * h
h = o/sin(theta)

Noting of course that theta defaults to radians.

Or, do you mean radio triangulation by directional signal propagation
strength? The equations for that are a bit beyond me currently, but I'm
studying.

Or, do you mean drawing a triangle in Tkinter?

from Tkinter import * 

#Do some stuff to create a Tkinter canvas in a window, call it... myCanvas.

pointA = [100,100]
pointB = [200,100]
pointC = [150, 0]
triangle =
myCanvas.create_polygon(pointA[0],pointA[1],pointB[0],pointA[1],pointC[0],po
intA[1])

...Not that I know if that will work or not. I'm just going on some outdated
Tkinter tutorials; I daresay the syntax of passing co-ordinates has changed
(I'd hope so.)

Can you be more specific?
