Heres a tip how you can do it.
You need to rotate a couple of images using an angle?Try this code:
image1.RenderTransform = new RotateTransform(); ((RotateTransform)image1.RenderTransform).Angle =angle;
image1.RenderTransform = new RotateTransform();
new
RotateTransform();
((RotateTransform)image1.RenderTransform).Angle =angle;
