Angles are measured using degrees, ranging from 0 all the way to 360 degrees in one full turn. There are many different types of angles, but possibly the most easily recognisable is the right angle.

Electronic enthusiasts that need to measure angles on their robotic arm or other projects may be interested in a new proximity sensor that has been created by William Moore called the Protractor.

Actually, you would have to take your angle measurement and subtract from 90° to get your latitude. Also, there is a straw on top of my protractor to assist with the aiming—and it looks cool.
