+27 Rectangle EFGH is rotated 90° clockwise around the origin.
What are the coordinates of the image of point F?
Can you be a little more specific ? "it didn't work" isn't very helpful.....
here is where you will have to click on after you FIRST click on 'image'
BTW I uploaded THESE images this way......so it works....sometimes it fails though....maybe try again?
Sometimes people just post links to images, though I don't encourage that method.....I won't usually answer if I have to go click -linking around ! 
+118667 You could just give the original co-ordinates of the points.
But if you are are going to ask more questions it is in your interest to play around with the image loader until you can get it to work.
Where is the picture? Is it an image file on your computer or is it on the internet?
