Turtle graphics

[maiden128]

Hello,

I'm new and I was wondering how to do these things in python using turtle graphics... but don't know how to do it:

1.Write a program that draws a red line connecting two points (-39,48) and (50, -50) and displays the coordinates of the two points.

1. How to draw a triangle like this in turtle:

1. Write a program that display the result of 4 X (1-1/3+1/5-1/7+1/9-1/11) and 4 X (1-1/3 + 1/5 -1/7+1/9-1/11+1/13-1/15)

please be nice... thanks.
