What is the only state in the United States that does not have a flag in a shape with 4 edges?

The answer is Ohio because the state flag is not shaped like a rectangle with four edges. Instead, it is unique in design, as it features a swallowtail shape, with a large blue triangle on the left side containing 17 white stars symbolizing Ohio being the 17th state to join the United States. The rest of the flag consists of alternating red and white horizontal stripes. This distinctive flag design sets Ohio apart from the other 49 states and reinforces its individuality and identity.
