Degrees and minutes are units of measurement used in geometry to measure angles. Degrees are the larger unit and are equivalent to 60 minutes. This means that 1 degree is equal to 60 minutes.
To convert degrees to minutes, you need to multiply the degree value by 60. For example, if you have an angle of 45 degrees, multiplying it by 60 would give you a measurement of 2700 minutes.
The symbol for degrees is ° and the symbol for minutes is '. Together, they can be used to represent an angle measurement in degrees and minutes. For example, 45 degrees and 30 minutes would be written as 45°30'.
To add or subtract angles in degrees and minutes, you need to convert both angles to decimal form. For example, if you have an angle of 45 degrees and 30 minutes and you want to add it to an angle of 30 degrees and 15 minutes, you would convert both angles to decimal form (45.5 and 30.25) and then add them together (45.5 + 30.25 = 75.75). Finally, you would convert the decimal answer back to degrees and minutes (75.75 = 75 degrees and 45 minutes).
To measure angles using a protractor, place the protractor on the angle so that the midpoint of the protractor's baseline is on the vertex of the angle. Then, align the baseline of the protractor with one side of the angle. The number on the protractor's scale that lines up with the other side of the angle is the measurement in degrees. If the angle also has minutes, you can use the tick marks on the protractor to estimate the measurement in minutes.
