Potato
Fold the fabric on the diagonal so that one side edge is on the top edge. If you then cut along the shortest vertical edge, and unfold, you now have the largest square possible.

First identify which are the long sides. Paper can be held either in portrait or landscape position. In portrait, the longer sides are the sides, and the shorter sides are the top and bottom. In landscape, it is the opposite. Since your question didn't indicate portrait or landscape, I will give the directions for portrait. For landscape, just turn the paper so that the longer sides are top and bottom. For portrait, make sure that the longer sides are at the sides. Now fold the paper so that the longer sides touch, then press the paper to make a crease along the fold. For landscape, fold the paper so that the shorter sides touch, and press the paper to make a crease along the fold.
It is simply called its top.
The top number is called the numerator.
Long Edge
The top edge of a paper typically has a margin of 1 inch. The beginning of the bibliography is usually placed 2 inches from the top edge of the paper. Therefore, the number of inches from the top edge to the beginning of the bibliography is 1 + 2 = 3 inches.
This question is not clear, but my best guess is that you are looking for landscape (print with the long edge of the paper on the top).
The top edge of a glass or cup is called the rim.
An edge is a place where two faces (or sides) are connected, similar to if you folded a piece of paper in half... the folded part is like the edge of a prism. The vertices are the points, like the top of a triangular prism or the top of a pyramid.
landscape
Landscape and portrait have nothing to do with the kind of paper. They indicate the orientation of the paper in relationship to what is printed on the paper. Landscape prints with the long side of the page at the top (the side is the shorter width), while portrait prints with the long side of the paper to the side (the top is the shorter width).
center
The top of a pencil is called an eraser. It is used to remove graphite marks from paper by rubbing it over the pencil strokes.
a piece of paper is a 3D object it has a front and back face + two side edges + a top and bottom edge = 6 sides a piece of paper has 6 sides
Group of A4 sheet is called as ream.......
Top edge, bottom edge, wherever. A good design is one where the user does not have to search for the scale.
