Assuming that the author of the question means "how long is the fold in a rectangular 6X8 piece of paper folded so that two opposite corners meet", the answer is as follows:
Folding a piece of paper is like reflecting one side of the fold through the fold. Setting a coordinate system with the origin on the bottom left corner of the paper (and assuming we are folding the top right corner to meet bottom left corner) the line joining the two corners has a slope of 8/6. The fold must be perpendicular to this (it is a reflection!) so it has slope -6/8 and traverses a horizontal distance of 6. Therefore the fold is a line segment of x displacement 6 and y displacement -36/8 = -9/2.
Using pythagoras, the length of this line segment is sqrt(64 + (81/4)) = sqrt(337)/2 = 9.18 (note that we were not given units, so our answer is unitless as well)...
Yes, for example if you fold a piece of paper the paper wishes to remain in the folded position.
It's physically impossible to fold a piece of paper more than 7 times.
It is generally believed that an A4 piece of paper can be folded in half approximately seven to eight times due to the thickness of the paper increasing with each fold, making it increasingly difficult to fold further.
Fold it into half, then another half again.
That's called a hamburger fold.... mmmmmmmmmm hamburger.
Fold a piece of paper hamburger style. About 1 inch down from the top of the folded paper, start an arc and loop it down to the corner of the fold. Cut along this figure you made.
They are called fold lines or perforated lines. They indicate where the paper should be folded or torn.
In theory, paper can be folded in half more than 7 times, but it becomes increasingly difficult as the number of folds increases. The thickness of the paper and its size are limiting factors that make it practically impossible to fold a standard piece of paper more than 7-8 times.
To fold a piece of paper into an envelope without using tape, follow these steps: Fold the paper in half horizontally. Fold the top corners of the paper down to meet the center crease. Fold the bottom corners of the paper up to meet the center crease. Fold the bottom edge of the paper up to meet the bottom of the triangle created by the previous folds. Tuck the top flap into the pocket created by the bottom fold. Your paper is now folded into an envelope shape.
the bottom is already folded
Here are some examples with the word fold in a sentence. Ex 1: First you fold the paper this verticaly. Ex 2: Please fold the paper and put it in the envelope. You can also use it with ED at the end as foldED. Ex 1: I folded the paper and stuffed it in the envelope. Ex 2: After I folded the paper verticaly, I drew a picture of a dog. =)floppyj10
To create a square piece of paper for origami, start with a rectangular piece of paper. Fold one corner of the paper diagonally to the opposite edge to create a triangle. Cut off the excess paper along the folded edge. Unfold the paper to reveal a square shape.
