:[[User:Tomruen|Tom Ruen]] is correct. "Isogonal" means "1-isogonal" -- all vertices are the same. "2-isogonal" means there are two types of vertices, so the two basket weave patterns are not isogonal. If you have trouble seeing this for the basket weave patterns, look how you can see four lines coming together for certain vertices and for other vertices only three lines coming together. Another way to see this is by noticing that some vertices are surrounded by four rectangles and some by three. If you omit the basket weave patterns, you can say the others are isogonal. I think it would be better to leave the basket weave pattern and just avoid discussion of isogonal because it might confuse readers. --[[User:Seberle|seberle]] ([[User talk:Seberle|talk]]) 20:53, 12 April 2011 (UTC)
== "The two diagonals are equal in length and bisect each other. Every quadrilateral with both these properties is a rectangle." ==
This fact is given under "miscellaneous" but does it not belong as a "characterization"? This seems rather inconsistent to me. [[User:TheGrappler|TheGrappler]] ([[User talk:TheGrappler|talk]]) 16:39, 17 February 2017 (UTC)
