Angle Units & Angular Misclosure: DMS, Decimal Degrees and the (n − 2) × 180° Check
This lesson is part of the course
In this lesson
You convert five observed interior angles from degrees-minutes-seconds into decimal degrees, compare their sum with (n − 2) × 180°, spread the angular misclosure equally over the stations and write the adjusted angles back as D-MM-SS text.
