You have strip 1 and 2 connected at the ends (flattened) see pic..

Using your intuition answer;

1)Can 1 be made to look like 2?

2)Assuming edges of paper are parallel, and that both strips of paper are the same length. Would the distance from point A to point A be the same as the distance from point B to point B, assuming you traveled parallel to the paper for both A and B.

3)Are they even mobius strips?

Spooooon!!!

1. Yes. You just need to flip one of them.

3. Yes, they are

Have you tried makng them and flipping on of them?

And, they are not Möbius strips.

Sorry, The flipping did not work.

The second one is a mobius strip. I think the first one is too.

The first one isn't. The second one is. The first one has a 3x180 degree turn, while the second one has just 1.

Well as long as there are an odd number of 180 degree turns then it's called a mobius strip. As long as it has only 1 face.

Well, not really. First of all, the number of 180 degree turns must be odd. Second, it depends on the definition of the Möbius strip.

I have edited my post and it says odd now. Anyway, odd is enough. In Vietnam any strip with twists are called Mobius strip, whatever the number is, but internationally it's either a) 1 twist b) odd number of twist. I like the b definition more.

Well, it is true that topologically, as long as the parity is the same, the strips are the "same". I do not remember what the relation is called, but, either way. one cannot be turned into the other without going to the 4D space.

I agree. Anonymnistefy, have you seen that it has only one face?
