Talk:Duocylinder

Duocone?

Seeing a duocylinder as the limit of a duoprism, and the duopyramid as the dual of the duoprism, I see the dual of the duocylinder could be called a duocone as two orthogonal co-centered circles connecting every points of one circle to every point in the other. This is similiar as the limit of a bipyramid is a bicone (which has been defined), connecting a 2D circle to a 1D circle (2 points). SockPuppetForTomruen (talk) 22:38, 19 December 2012 (UTC)
