You can determine your geographical latitude by measuring the angle of the pole star above the horizon, which corresponds to your latitude on Earth.
To tell your geographical latitude from the stars, you can observe the angle of the pole star (Polaris) above the horizon. This angle is equivalent to your latitude on Earth. So, if Polaris is observed at an angle of 45° above the horizon, you are at a latitude of 45° north. At the North Pole, Polaris appears directly overhead (90°), while at the Equator, it appears on the horizon (0°). Therefore, by measuring the angle of Polaris above the horizon, one can determine their latitude.
