Best way to do corners in electric fencing?

Stick another post in the ground at the opposite side and make like a triangle with the wire/tape/rope going through both post and stick them in the ground like this ^ (Lol) dont know how to do pictures! (post-tape-post) /*\...make sense?
 
What we do to stabalise a corner is, the post that your using for the corner, put another behind it but push it into the ground at an angle so the bottom of the 2nd post is closer than the top. Get a piece of bailing twine and tie it through one of the holes on the post pull tight and tie to the top of the 2nd post, this keeps it upright and stops it falling in. Has never failed with me!
