- I have (had) the following problems which I`d like to pose in public:
-
- 1.) How can I fold a pentagon from a quadratic sheet of paper easily ?
- How can I fold an approximate (regular) pentagon from a quadratic sheet of
- paper easily ?
-
-
- 2.) On a sheet with quadrats on it (as used in schools for writing)
- I'd like to draw an equal sided triangle where every one of the
- three points should be on a edge of a quadrat.
- If this is not possible, why not ?
- How can I draw a good approximation of an equal sided triangle
- with every on of the three points on the edge of a quadrat.
- (Make use of the fact that the human eye doesn't see horizontal
- and vertical lines at same sizes)
-
-
- I dont know the answers. If you have any or find any I would be glad if you could
- send them to me by e-mail (if nobody else is interested)
-
- Thanks
