First reply lost; quick retry. I’m like MX but can see ‘Magic Eye’ etc. so 3D for not require “Minds Eye”! It’s ’my Eye’ that I assume is moved to help it interpret what it sees; and (developed by extra use) Logic.

They took seconds to do; With no thought of imagery to do it; How do people use that? 1) clockwise from open edge is circle, blue orange; as was the first answer offering. 2) looking at it the 3D view popped out; Purple blue orange into the shape on a surface. 2 and 3 had a differently bent shape; and all the colours were the same. The question said only 1 was matched (used “is”); so a little while was spent looking for the error; as I assumed it was not in the question. (=> “Which of the 4 match the first?”) 3) first glance showed only 3 faces in answer; so must compare answers; rather than learn question. Answer 1 has green and blue faces L-R across the nearest point. Answer 1 and 2 match the shape folded to see the shown surface; and 4 matches folded the other way (if it’s a 2 sided printing). Having a clear error and not saying if the flat shape is single or double side printed is wrong!
