Hi guys
Im practicing the PAT and im doing fine with all the other sections...
BUT this pattern folding section is driving me crazy.
The answer choices A and D look the same to me and every question I get wrong is this pattern
It looks like an enantiomer(?)... I don't get how to tell the difference between these answer choices
Can someone please please explain to me how to tell the difference?
Thank-you!! 😀

A has to be facing left. It doesn't fold out of the page only into the page. So it is either facing left or upside down facing right.

Basically, the front face of A doesn't exist. As 510586 said, the shapes only fold into the page and the front face of A is as if you looked at that piece from behind. It's flipped over a Y axis if you can see that, but we have no way of seeing what the back of that piece looks like, so it must be incorrect.

Ahh I see... I didnt know it only folds into the page.
Wow that makes this section so much easier...
Thanks!
