How do you find the angle of latitude? Use the sight line on the top of the aiming beam to align the beam with the North Star. Use the protractor to measure the angle between the beam and the horizon (which is 90º to the plumb line). This angle is your latitude.
Then, How do you find the degrees above the horizon?
You can also use your clenched fist as a sextant to measure the height of the moon, star, or planet above the horizon. Your clenched fist, correctly held, will roughly measure off 10-degrees. So you can use your fist to make a reasonable guesstimate of degrees either horizontally or vertically.
Secondly, What is latitude angle? Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.
How do you use Polaris to find latitude?
Keeping the 0° edge flat against the horizon, lift one arm of the compass until it points directly at Polaris. Read off the angle. This is the altitude of Polaris from your location on Earth. This corresponds to your latitude.
How do you solve latitude and longitude?
Mark how much distance is between the southern parallel to your location. Add this to the latitude of the southern parallel to get the latitude of your location. To measure the longitude you must place the ruler diagonally on the west and east meridians with the ends of the 2 ½ minute ruler touching both meridians.
How do you find 10 degrees above the horizon?
If you hold your fist at arm’s length and place your fist resting on the horizon, the top will be about 10 degrees. Appears is the location in the sky where the station will be visible first. This value, like maximum height, also is measured in degrees from the horizon.
How do you find the degree in the sky?
MEASURING THE SKY
- Stretch your thumb and little finger as far from each other as you can. …
- Do the same with your index finger and little finger. …
- Clench your fist at arms length, and hold it with the back of your hand facing you. …
- Hold your three middle fingers together; they span about 5 degrees.
How do you calculate degrees in the sky?
Hold your hand at arm’s length and close one eye. Make a fist, with the back of your hand facing you. The width of your fist will approximately be 10 degrees. This means that any two objects that are on the opposite ends of your fist will be 10 degrees apart.
Which latitudes correspond to the North and South Pole?
The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S. Like the poles, some circles of latitude are named.
How do you find latitude and longitude on a map?
Latitude is indicated on a map by a series of evenly-spaced horizontal lines running from one side of the map to the other, while longitude is indicated by a series of evenly-spaced vertical lines running from top to bottom. Look for numbers along the edges of the map giving coordinates for each line.
Why is Polaris not always the Pole Star?
The spin axis of the Earth undergoes a motion called precession. … Earth’s spin axis also precesses. It takes 26,000 years to go around once! So now you can see why Polaris will not always be aligned with the north spin axis of the Earth – because that axis is slowly changing the direction in which it points!
How do you find Polaris?
How do you find the North Star? Locating Polaris is easy on any clear night. Just find the Big Dipper. The two stars on the end of the Dipper’s “cup” point the way to Polaris, which is the tip of the handle of the Little Dipper, or the tail of the little bear in the constellation Ursa Minor.
How do you find your latitude using your fist and the night sky?
If you are in the Northern Hemisphere, you can use your hands to find your current location’s latitude. To do this, stretch your hands in front of you and measure the angle between the visible horizon and the North Star. This angle is your latitude in degrees.
How do you find the bearing angle?
How do you find the distance of an angle?
Calculate the sine of the angle to find the total distance between objects, or the hypotenuse. For the example, the sine of 60 degrees is √3/2 or 0.866. Divide the height of the object by the sine of the angle. For the example, dividing 150 by 0.866 results in 173.205.
How do you find the coordinates when given the angle and distance?
If your starting point is (0,0), and your new point is r units away at an angle of θ, you can find the coordinates of that point using the equations x = r cosθ and y = r sinθ.
What is 15 degrees above the horizon?
In early twilight, within half an hour of sunset when the western sky is pale blue, planet Venus turns our heads to receive its brilliant light, now 15 degrees above the horizon.
How many degrees is an angle?
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees .

How many degrees wide is the Moon?
Since 1 radian = 57.3 degrees, the angular radius of the Moon is 0.0045 x 57.3 = 0.26 degrees, so its diameter is 0.52 degrees as viewed from Earth.
How do you measure an angle with your fingers?
Measuring Sky Angles
- Stretch your thumb and little finger as far from each other as you can. …
- Do the same with your index finger and little finger. …
- Clench your fist at arms length, and hold it with the back of your hand facing you. …
- Hold your three middle fingers together; they span about 5 degrees.
Which is the biggest circle on the Earth?
The biggest circle of the globe is an equator. As the equator passes through the centre of the earth it is considered as the largest circle of the earth.
How many parallels are drawn on the Earth?
Explanation: The Earth is divided by the Equator into two equal halves known as the Northern Hemisphere (with 90 parallels) and the Southern Hemisphere (with 90 parallels). These 180 parallels along with the Equator make a total of 181 parallels across the globe.
Why do the two circles of latitude never touch?
Circles of latitude are often called parallels because they are parallel to each other; that is, planes that contain any of these circles never intersect each other. … The Equator is the longest circle of latitude and is the only circle of latitude which also is a great circle.
