The term "090°" typically refers to a direction on a compass, indicating due east. In navigation, this angle is measured from true north, which is at 0°. A compass rose often displays this orientation, helping travelers and navigators determine their path. In various contexts, "090°" can also relate to coordinates in mapping systems, where it signifies a specific point in a grid. This can be useful in fields like geography, aviation, and maritime navigation, where precise directions are crucial for safe and accurate travel.
