If you go counterclockwise the degree measure is positive and when you go clockwise the degree measure is negative. 2. ** Coterminal angles ** are angles that if you add 360 degrees or subtract 360 degrees the angles will essentially be the same but just with the addition or subtraction of one full rotation of the circle. A degree is divided into 60 equal parts called minutes and each minute is divided into 60 equal parts called seconds. Knowing this you can break down a decimal degree into degrees, minutes, and seconds format. For example, say you have 44.235 degrees, the right side of you decimal(44) is the degrees. Then take the left side of the decimal and multiply it by 60. You will get 14.1; the 14 is your minutes. Then take the .1 and multiply it by 60; You will get 6, this is you amount of seconds. A different process is used to convert degrees-minutes-seconds into a decimal degree. For example say you have 44 degrees, 12 minutes, and 30 seconds, 44 being your amount for degrees is on the left side of the decimal. You then take the 12 min and multiply it by 60. You then multiply 30 by 360. You add the two decimals (.2 and .0083) together and you get your answer of 44.2083.
