Usually Miles or Kilometers
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.
Miles or Kilometers
metres, kilometres .................................
To measure the distance of stars you have to measure by light years.
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.
Kilometers
Because it is a large number, suitable for large distances. Astronomers also like to use the unit Parsec.
to measure long distances
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.
Usually light-years, or parsecs.
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.
Small distance or height is measured in millimeter. Larger quantities are measured in kilometers.
