File:Flag of Ohio test.svg

I made a hand-coded flag of Ohio using the construction sheet from the site Zscout370 gave (see file history), but the exact size and placement of the stars in my version is different from that of the stars in the current one. I don't know if the current file is inconsistent with the construction sheet, of if I misread some of the numbers. SiBr₄ (talk) 11:13, 4 January 2013 (UTC)

When I uploaded the first image based from that sheet, I said it was a work in progress since I wasn't able to see what the size each star was and some stars I was not able to place correctly (but keep in mind I was drinking bourbon and it was New Years Day). So yours is a better version and I will go ahead and upload that. User:Zscout370 ^{(Return fire)} 03:49, 5 January 2013 (UTC)

So File:Flag of Ohio test.svg can now be deleted? (File:Flag of Syria test.svg is also still there.) SiBr₄ (talk) 19:14, 7 January 2013 (UTC)

The Syrian test is a different can of worms, so I will avoid deleting that for the time being. User:Zscout370 ^{(Return fire)} 04:43, 8 January 2013 (UTC)

Construction

A much higher resolution image of Eisenmann's original drawing (thanks to Mxn for finding and uploading it!) shows the radius of each star is 5/16 unit, not 1/3. I've reflected this in my newest upload. I'm trying to make sense of the details for the placements of the stars, but the sheet contains various geometrical contradictions: it implies that each angle bisector of the blue triangle is or should be perpendicular to the opposite sides (which is only true for equilateral triangles), and that the radius of its incircle is rational (the sheet shows it as 2.5 units; using geometric construction it's ±2.472). For this reason I've kept the circle radii and multiples-of-thirty-degrees assumption from the previous version for the star placements. SiBr₄ (talk) 11:38, 22 September 2014 (UTC)

I've finally corrected the locations of the stars, using the textual construction below the graphical one. The first of the contradictions in the graphical sheet turns out to not be an issue, as the pairs of line segments AO–OI and DO–OM need not be (and indeed are not) collinear. The second contradiction does exist, though, so I used the textual description for the circle radiuses: the circles forming the "O" have rational radiuses, while those defining the star positions are half-unit offsets of the triangle's incircle. This means only the "1/2" measure between the outer circle of the "O" and the inner circle of stars in the graphical sheet is inconsistent with the text below it.
