Teach Astronomy - Measuring Angles

http://www.teachastronomy.com/ Angular measurement is an important part of astronomy. When you want to quote the position of an object on the sky you give it in terms of two different angles. The basic unit of angular measurement is a degree. There are 90 degrees in a right angle and 36
