I was wondering about MS paint and stumbled upon certain interesting problems. Here they are.

**Problem 1:** Can you draw an equilateral triangle in MS Paint?

**Problem 2:** Can you draw a regular hexagon in MS Paint?

**Problem 3:** Can you draw a regular polygon having odd number of sides in MS Paint?

**Rules:** You cannot use any aid to make measurements of any kind (length or angle). You can only use MS Paint (obviously). You are not supposed to use the co-ordinates to make measurements of any kind (length or angle). However, you can use the co-ordinates for precise placement of your mouse pointer.

TopNewestIt's impossible; drawing on MS Paint requires the vertices to be lattice points, and it's a well-known result that a regular polygon that is not a square cannot have their vertices on lattice points (using that if \(a,b,c\) are rationals and \(\cos a\pi = b, \sin a\pi = c\), then \(2a\) is an integer).

Of course, assuming that MS Paint's canvas is infinitely divisible (so it's basically a plane of reals times reals), then it's the usual compass and straightedge problem.

Read my comment below. The equilateral triangle and regular hexagon can be constructed (and should looks okay if the screen resolution and the size of the computer screen is 1:1). Only the pentagon is impossible to construct.

This video shows you how to make a 60 degree angle, an equilateral triangle and a hexagon. Youtube video I hope I didn't break any rules. Plus, constructing a regular pentagon is impossible in Windows XP paint.

I think I got it. picture

err how do you draw the circles so precisely?

In Windows 7, you can make a hexagon and a pentagon. Plus, you didn't say a REGULAR hexagon. So, problem 2 and 3 have been solved. But I don't know how to make equilateral triangle.

Problems 2 and 3 have been revised. Try them out now :P

Heh. I knew it you meant that way. But in Windows 7, I just realized that I can solve those three puzzles easily. Okay, let's say that you do it in Windows XP. I'll try solving these problems. Because I might got it. Might. Hehe.

After choosing a tool, let's say a pentagon, while holding the shift key, you can make a regular pentagon. That will also work on other tools.

I think making a pentagon in Windows XP paint is impossible.
