The Sum Rotation Puzzle

This puzzle i found has two parts. The first one being too easy and anyone can do that easily. Now when you look to the second part you will have to shake your minds. Lets work through this riddle too. Have a walk through:

1. The numbers 1,2,3,4,5,6,7,8,9 i.e 1 through 9 are arranged in a 3x3 matrix in such a way that the top two rows sums up to give the bottom row. Now thats fairly simple.

2. The twisting part is : If the matrix is rotated 90 degrees to its left it must give the similar condition as in part 1.

Now you have got to find out what is that arrangement!!!

Note : Please don't even think about assuming 9 as 6 or vice versa while the flip takes place. They remain the same!! :-)
