Because they were once joined together in a single large continent (Pangaea), which was broken apart by plate tectonics. This formed separate landmasses, but they may be pushed together again in the far future.

South America and Africa are the most notable continents that fit together like a jigsaw puzzle (as all continents do). This suggests that continents were connected at one time and that they are mobile and constantly moving.
If you look at a picture of south America and Africa and then you cut them out they should fit together like a puzzle piece!
Abraham Ortelius was the first to note the remarkable fit of the coastlines of South America and Africa in the year 1596. In 1858, geographer Antonio Snider-Pellegrini made two maps of the globe showing his version of how South America and Africa may once have fit together, then later separated. Later, in the early 20th century, Alfered Wegener developed the (incorrect) theory of "continental drift" that revived interest in the subject and lead to the current theory of plate tectonics.
South America extends further south than Africa.
Probably the west coast of Africa with South America.

Alfred Wegener observed the apparent fit of the coastlines of South America and Africa, suggesting they were once joined. This observation helped support his theory of continental drift, which proposed that continents were once connected in a single landmass called Pangaea and drifted apart over time. This theory laid the foundation for the modern theory of plate tectonics.

Yes, Alfred Wegener observed that the coastlines of South America and Africa appeared to fit together like puzzle pieces. This observation was a key piece of evidence in support of his theory of continental drift, which proposed that the continents were once connected as a single landmass before drifting apart over time.

Alfred Wegener noticed that the outlines of the continents seemed to fit together like pieces of a jigsaw puzzle, particularly the coastlines of South America and Africa. This observation led him to develop the theory of continental drift.
