Sum of the IA = (# of sides - 2) * 180 =
Step #1 – Sum up the five interior angles listed above. Remember that any number over 60 needs to have
units removed by groups of 60 seconds or 60 minutes.
Step #2 – Calculate the desired Sum of the Interior Angles = (# of sides – 2) * 180.
Step #3 – What is the difference between the Desired Sum of the Interior Angles and the sum of the five
angles above?
Step #4 – Take the difference between the two totals and divide by the # of sides. You may have to reduce
Degrees, Minutes and Seconds down to Seconds Only. The result will be the Correction Factor for each
angle.
Step #5 – If the sum of the five angles is more than your desired goal; create the New Interior Angles by
subtracting the Correction Factor. If the sum of the five angles is less than your desired goal; create the
New Interior Angles by adding the Correction Factor.
Step #6 – Sum up the New Interior Angles. If the total matches your Desired Sum of the Interior Angles,
then you have completed this step correctly.
