> Title: Classifying Quadrilaterals
>
> In the definitions of Book 1 of Euclid's Elements one can find a
rudimentary classification of the quadrilaterals. By and large, the same
classification is still taught today. Over time, however, various changes
from Euclid became commonplace and at least one new type of quadrilateral
was introduced. In this presentation, we will look at the history of the
classification of quadrilaterals from the mid-16th century through the 19th
century. In close connection with this, we will also have a look at the
history of the notion of the general or "irregular" quadrilateral, i.e. the
class of quadrilaterals generally not included in the usual classifications
of the quadrilateral.
