At the Berlin Conference, the European powers represented resorted into creating arbitrary geometric boundaries on Africa's map to ease out the division of the interior region among themselves.

Explanation:

At the time of the conference, only the coastal areas of Africa were colonized by the European powers. At the Berlin Conference the European colonial powers scrambled to gain control over the Interior of the Continent. The conference lasted until February 26, 1885 – a three month period where colonial powers haggled over geometric boundaries in the interior of the continent, disregarding the cultural and linguistic boundaries already established by the Native Indigenous African population. What ultimately resulted was a hodgepodge of geometric boundaries that divided Africa into fifty irregular countries.
