	Comments:	A square is always a quadrilateral, but the opposite is not true. Google images shows some squares for 四角形, but if that is to be a gloss here then I think it should be a separate sense.

	Comments:	世界大百科事典 specifically says that this is "development" in English, and the definition looks like it matches up with the EN Wiki definition of development. But the JP Wiki page for 展開図 is linked to the EN Wiki page for Net, and they seem to be talking about the same thing. Neither of the EN Wiki pages for Net and Development mention each other, and the page for Development is beyond me, so I'm not sure how related the two terms are.

	Comments:	I can't find a kanji for this verb. Only thing I can imagine it being would be 閃　since you got 閃く (ひらめく) and maybe ひらつく　would be an alternate reading. Or maybe it originates from ひらひら and has no kanji associated at all.
