How to draw a square with 3 lines??

Answer 1

You can't... the only closed figure you could make would be a triangle.

Answer 2

First, draw a square with four equal sides. Inside of it, draw 3 straight lines. The riddle does not mean to draw a square made out of 3 lines.

Answer 3

It's a trick question.

You can do it several ways:

1) By turning the paper while drawing a line; or perhaps folding it (I think this is cheating)
2) Drawing a "u" shape with one line. Then close off the ends of the square with two other lines
3) MathForum.org had this answer: (formats poorly on Yahoo, click the link)

A
/ | DA, AB, and BC are the three lines.

B---+-C The same idea works for "1" as well.

Answer 4

Ok try this then.

Draw two lines that cross at right angles, but do this on a torus not a flat plane. Extend these lines making sure that they go through the "hole in the doughnut". They will cross again, possibly a number of times.

If the size of the torus is carefully chosen the sides of each "square" could be made equal.

Oh damn, I've only used two lines. Not sure what to do with the third, sorry.

Answer 5

You would have to draw a u-shape with one line, then add two straight lines perpendicular to the straight parts to form a square.

Answer 6

This is impossible! If it is a closed shape, that is. This would just make a triangle. However there are some methods, such as halving one of the lines, leaving it open (like an open box shape) or using one side of the paper as a side.

Answer 7

Use one edge of the page as your 4th straight line in you square.

Answer 8

you cant it wouldnt be a closed figure
