Observe the following angle indications and their respective readings:
15th (reads "15 degrees")
45º50 '(reads "45 degrees and 50 minutes")
30º48'36 "(reads" 30 degrees, 48 minutes and 36 seconds ")
In addition to the protractor, there are other instruments that measure angles with greater accuracy. As examples we have the theodolite, used in surveying, and the sextant, used in navigation.
The representation of the measurement of an angle can also be done through a lower case or of a number.
a shallow angle or half turn measures 180º.
O one turn angle give me 360º.Next: Angle Measurement Issues
