Thank you. There is something else too. I always taught that the exterior angles of any polygon total 360 degrees. That is to understand that an exterior angle is the angle outside the polygon which is formed between one side and the other side produced on a little way.
No, the sum of all exterior angles cannot always sum to 360. The sum of an exterior angle and it's corresponding interior angle will always add up to 360. The total sum of exterior angles will depend on the number of nodes. You can confidently use the equation I show on the video. Please let me know if that helps. Please do not forget to subscribe to the channel, I will appreciate it.
I think we define the exterior angles differently. In mathematics each interior angle and its exterior angle are supplementary, as the 2 angles form a straight line. I suspect that in surveying each exterior (or outside) angle together with the interior angle make 360 degrees. It just means we mean different things by the words “exterior” angle.
If the measure of two angles added together equals 90, then the angles are complementary to each other. If the sum measured of two angles is 180, then the angles are supplementary. Hopefully this will help you clear it up. Thank you for watching.
