By the countries that occupied them in the 1800's
European colonial powers primarily used geographical features such as rivers and mountains to draw new boundaries for African countries during the Scramble for Africa in the late 19th and early 20th centuries. In many cases, these boundaries were drawn with little regard for the cultural, linguistic, or ethnic makeup of the local populations, leading to tensions and conflicts that persist to this day.
States with straight boundaries were often created through treaties, surveying techniques, or cultural reasons. States with irregular boundaries, like those in Africa, were often drawn by colonial powers without consideration of natural or cultural features, resulting in arbitrary divisions. In some cases, irregular boundaries may follow natural features like rivers or mountains.
Most state boundaries are not straight line segments because they often follow natural features such as rivers or mountain ranges, historical boundaries, or treaties between different groups or nations. These boundaries were typically drawn to reflect a combination of physical and cultural factors that shaped the development of the area.
Africa and South America have edges that are not all on plate boundaries. For example, the coast of Africa along the Atlantic Ocean is a passive margin, and the edges of South America along the Pacific Ocean have a mix of convergent and transform plate boundaries.
The Europeans created boundaries in Africa during colonization to divide the territory among themselves, avoid conflicts over territories, and facilitate control and exploitation of resources. It allowed them to establish clear lines of control and administration over the various regions and peoples in Africa.
Lolwut.
The African political boundaries were drawn without regard for ethnicities. Apex
states!
Simply put, no. Geometric political boundaries effectively separate 2+ pieces of land/territory, but not the people. Take Africa for example. Since Africa's borders were arbitrarily drawn by the British, they didn't take the hundreds of tribes in Africa into consideration. Plenty of Africans were in the same tribe but they were living, and being separated by, the borders.
Africa is a good example of geometric boundaries. When Europe had control over Africa around 1884, boundaries were drawn according to Europe's egotistical desires. Tribes, cultures, and historical ways of life were not taken into account when the borders were created, creating much conflict between native peoples. Conflict and instability are common with geometric boundaries because usually outside forces with selfish desires determine these.
Geometric boundaries
They led to unstable goverments
poorly drawn maps cause them to argue about boundaries
over cheeseburgers at Mcdonnalds!

The new boundaries caused confusion and conflict.
