Answer: The Sinai Peninsula
Sinai is a triangle shaped peninsula, located in the Asian continent and politically belongs to Egypt (this is why this country is considered a transcontinental land).
It is important to know that the border between Africa and Asia is not clearly defined. However, the Sinai Peninsula is often considered to be this border.
Although this peninsula divides the African continent from the Asian continent, many authors consider that the true boundary between both continents is the isthmus of Suez.
