A nonagon
The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.
Nonagon = 9 sides Hexagon = 6 sides So answer = 3
a nonagon has nine sides and nine angles and nine corners. It comes from the Latin word 'nonus' meaning nine.
It is a nine sided figiure.
nonagon
Because nonagon means 9 sides
Not a regular nonagon.
A nonagon has nine sides.

"nonagon" is not a prefix.

A nonagon is a 2D shape so you cannot make a 3D nonagon!
Only if all nine sides are the same length.
Total sum of interior angles of a polygon of n sides is found by the equation: S = 180(n-2) For n = 9, S is 1260. Divide 1260 by 9 to get (for regular nonagon): =140
