The sum of the interior angles of a n-gon is (n-2)*180 So, (n-2)*180 = 1800 ie n-2 = 10 so that n = 12 It is a 12 sided polygon or dodecagon.
A regular 12 sided polygon each interior angle measures 150 degrees
If the internal angles are 170 then the external are 180 -170 ie 10 deg. The sum of external angles is always 360 deg so there are 360/10 ie 36 sides. Alternatively, the internal angles of an n-sided polygon always sum to (180n -360) deg, so each angle = (180n -360)/n ie ((180n - 360)/n = 170 ie 180n - 360 = 170n ie 10n = 360 so n = 36
The sum of the exterior angles of a regular polygon equal 360° . If one such angle measures 36° then the polygon has 360/36 = 10 sides.
The sum of the exterior angles of ANY polygon is 360 degrees.
Exterior angles: 360 Interior angles: 1440
The interior angles of a 10 sided polygon add up to 1440 degrees

A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
A 10 sided decagon has interior angles that add up to 1440 degrees

10 exterior angles add up to 360 degrees 10 interior angles add up to 1440 degrees Its perimeter is the sum of its 10 sides
If a dectagon is another word for a decagon then this is a 10 sided polygon. No matter how many sides it has, the sum of the external angles of a convex or regular polygon is 360°.
