Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees
Each interior angle in 12-sided polygon is 150 degrees.
The central angle of a n-sided regular polygon = 360 degrees / n. Hence, the central angle of a 15-sided regular polygon = 360 degrees / 15 = 24 degrees ============================
The interior angles of a 16 sided polygon add up to 2520 degrees If it's a regular polygon then each interior angle measures 157.5 degrees
Each interior angle measures 160 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Providing that it is a regular 38 sided polygon then each interior angle will measure: 170o31'34.74''
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
