Explain the multiple areas in which the boundaries of israel changed between 1947 and 1949?

Borders of Israel

The current borders of the State of Israel are the result both of war and of diplomatic agreements among Israel, her neighbors, and colonial powers. Uniquely, only two of Israel's five potential land borders are internationally recognized while the other three are disputed.[1] Israel's borders with Egypt and Jordan have now been formally recognized and confirmed as part of the peace treaties with those countries. The borders with Syria (Golan Heights), Lebanon (Shebaa farms) and the Palestinian territories (declared as the State of Palestine) are still in dispute.[2]

According to the Green Line of the 1949 Armistice Agreements, Israel borders Lebanon in the north, the Golan Heights and Syria in the northeast, the West Bank and Jordan in the east, the Gaza Strip and Egypt in the southwest. The border with Egypt is the international border demarcated in 1906 between the United Kingdom and the Ottoman Empire, confirmed in the 1979 Egypt–Israel Peace Treaty, and the border with Jordan is based on the border defined in the 1922 Trans-Jordan memorandum, confirmed in the 1994 Israel–Jordan peace treaty.
