One thing not conveyed by this image is that, if it is a representation of the following equation (as described on the English Wikipedia article):

${\begin{bmatrix}x\\y\end{bmatrix}}\mapsto {\begin{bmatrix}0&1\\2&1\end{bmatrix}}{\begin{bmatrix}x\\y\end{bmatrix}}+{\begin{bmatrix}-100\\-100\end{bmatrix}}$

Then in addition to the translation and skew, the blue triangle is also rotated 90º clockwise from the original red and the vertices should be labelled. 76.2.22.129 05:18, 24 September 2011 (UTC)
