Final answer:
Bangladesh can be uniquely identified on a world map by its strategic river network, including the Brahmaputra and Ganges rivers, which flow into the Bay of Bengal.
Step-by-step explanation:
To identify Bangladesh uniquely on the world map, one would look for a series of distinct geographical features. Bangladesh is located at the northern edge of the Bay of Bengal, on the eastern side of India, and is renowned for its strategic river network. The Brahmaputra River, known as the Jamuna River within Bangladesh, is a major waterway of the region, which, along with the Ganges, empties into the Bay of Bengal after flowing southward from the Himalayas through India. Bangladesh's shape does not resemble a boot, which is more characteristic of Italy, and while the flag design is unique, it's not a geographical feature that can be identified on a map. Therefore, the best answer to how one can uniquely identify Bangladesh on a world map would be due to its strategic river network, particularly the presence of the Ganges and Brahmaputra Rivers and their fertile deltas prone to flooding.
