Common Wisdom:
No, you cannot. This is because of a theorem by Leonhard Euler in the field of Graph Theory. I will state this in Graph Theory terms: you cannot find an Eulerian circuit in a graph where more than two vertices have an odd degree. The "y" shape creates three vertices that have an odd degree, thus this is impossible. Please see the link about the Euler path for details.
An alternative view of the question (and answer):
You are thinking inside the box. You are being trapped by constraints which you are assuming, but are not stated in the problem. Of course you can draw a "Y" without picking up the pen or overlapping the lines. Simply draw a "block" letter Y. See the "Y in a rectangle" page for an example. (And, I fail to see how a rectangle makes this problem more difficult.)
Note the elements that make the second answer feasible:
# Interpreting "draw a y" as a "block letter y".
# Interpreting the words "in a rectangle" as meaning that you do not have to draw the rectangle.
I think this is counter-intuitive, but intuition is a subjective thing. Both answers are valuable.
Crossing is almost the same as overlapping in the way ur using it. (P.s. use a pencil not a pen :D)
first of all draw a circle then don't lift your pencilsecondly draw a line halfway and keep your pencil therethirdly draw a line going left and keep your pencil therelast of all go round the bottom and draw a line from the right angle going back up to the halfway line and there you have it a perfect peace sign without taking your pencil off the paper.
Its easy, but you have to use a pencil. Right. Or you could lock the pen in place and move the paper.
get a pencil and some paper and draw a dove with the pencil onto the paper
With a pencil.

There is no such thing as a i triangle

No. You can have at most two vertices where an odd number of lines meet. The required figure has four.

If you can draw it without lifting your pencil
The drapes. Or a breath
you can draw anything with a pencil.
no impossible
Use A Ruler
all you have to do is draw overlapping humps.
