What is the only country in the world with a flag that doesn't have four right angles?

The answer is Nepal because the country's flag is unique and doesn't have four right angles. Instead, Nepal's flag is shaped like two overlapping triangles, forming a Pennon or a pennant. The larger triangle represents the country's majestic mountains, while the smaller triangle signifies Nepal's harmonious unity between its Hindu and Buddhist populations. This distinctive flag design sets Nepal apart from other countries in the world.
