When measuring angles one does so using degrees, minutes, and seconds.We can also use radians.
degrees True, but advanced mathematicians, although a lot fewer in number, are likely to use radians.
use a protractor to measure angles
A ruler or tape measure.
Use a ruler, place one end at 0 and where ever the other end is, thats how long the segment is. GOOD LUCK!
you would measure distances in centimetres, metres and kilo metres.
To measure the distance of stars you have to measure by light years.
Miles or Kilometers
metres, kilometres .................................
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.
For long distances use " Measuring Wheel". These give readings generally in Feet which can be converted to any unit by appropriate multiplication factors. Some of these are 1-GRIP ON 10000 ft measuring wheel, 2-Stanley 77 194 MW408 12" Aluminum Wheel Measuring Wheel In Feet/Inches
Kilometers
Because it is a large number, suitable for large distances. Astronomers also like to use the unit Parsec.
to measure long distances
The best unit to measure the distance from Fairbanks to Anchorage would be miles or kilometers. These units are commonly used to measure long distances between cities and are widely understood.
You can use the kilometer to measure small distances, but it is inconvenient to do so. A kilometer is a unit of measurement for a large distance. It is more accurate and practical to measure small distances using smaller units like the meter or centimeter.
In British countries, miles is an old-fashioned unit to measure distances. The modern, international, unit is the kilometer, equal to about 0.6 miles.However, miles as a unit of measurement for distances is still used throughout the US. We rarely use the metric system in the US.
