In response to pahio's correction, I've managed to draw right angles on the left and right hand triangles, but I can't get xypic to work for the third triangle. (I'm trying to learn xypic as I go). Perhaps someone can help. I'm trying
\[
\begin{xy}
,(0,24)
;(42,18)**@{-}
;(42,0)**@{-}
;(42,2)**@{-}
;(40,2)**@{-}
;(40,0)**@{-}
;(42,0)**@{-}
;(0,0)**@{-}
;(0,2)**@{-}
;(2,2)**@{-}
;(2,0)**@{-}
;(0,0)**@{-}
;(0,24)**@{-}
;(18,0)**@{-}
;(19.4,.94)**@{-}
;(18.46,2.34)**@{-}
;(17.06,1.4)**@{-}
;(18,0)**@{-}
;(42,18)**@{-}
,(9,-2)*{a}
,(44,9)*{a}
,(-2,12)*{b}
,(30,-2)*{b}
,(9,16)*{c}
,(30,12)*{c}
\end{xy}
\]
but nothing gets drawn for the elements using nonintegral coordinates. Is there a different way to do this?
Thanks,
Roger |
