Sighting the Sun at midday (when it is highest in the sky) is one of the best methods to determine latitude (of course you must know what day of the year it is too but that was relatively easy to keep track of).
You have to be very careful if you are in the middle of an ocean and on a ship bobbing on the waves to do this properly!
you find a straight angle across ur curtains
To find an acute angle you need to find out if it is less than 90 degrees.
You find the arc measure and then you divide it in half to find the inscribed angle
9o35'
180 - interior angle = exterior angle

Until GPS, or at least until LORAN, that's exactly how it was always donein the northern hemisphere.Navigators need another method, however, in the southern hemisphere,since the north celestial pole is not visible from there.
In the northern hemisphere, we used to rely on locating where Polaris is in the sky, which is almost directly over the North Pole. The angle of Polaris above the horizon corresponds to your latitude so Polaris helped many sea navigators to find their was north or south.
Sighting the sun or stars, but that only gave latitude. To get longitude required an ultra precise chronometer.
The angle between the north star and your northern horizon is approximately the same as your latitude north of the equator.
I believe it dates back to when the North Star was used to find latitude by ancient sailors. Degrees latitude was found by the angle between the North Star and the horizon. Since the North Star sits on the horizon at the equator the angle is zero therefore latitude is zero degrees.

You will notice that the angle makes with respect to the horizon. Typically, you will find that the angle will be 90 minus the latitude of the observer.
The Compass
Latitude is the north/south angle between the equator and any point of interest. Longitude is the east/west angle between the Prime Meridian and the same point. With the two numbers that describe it, you can find any point on Earth.
