A polygon is a closed 2-D shape with sides made from straight line segments.
The sum of the exterior angles of a polgon - no matter how many sides - is 360 degrees.
The shape you're referring to is call a decagon.
Heptagon
a polygon is a closed plane shape
it is usually called a heptagon or septagon. but we usually call it a heptagon. :)
how many sides does an polygonshave

An octagon is a polygon that has 8 sides
there is such a thing as an irregular polygon that has sides of different sizes. all REGULAR polygons however have equal sides
360/18 ie 20 sides
A polygon is a closed 2-D shape with sides made from straight line segments.
60 sides 180-174 = 6 360/6 = 60
It can be, if its sides all have the same length.In that case, it would also be called a 'square'.
It wil be a regular 18 sided polgon
If its a regular polgon and each exterior angle is 30 degrees then it will have 360/30 = 12 sides
The sum of the exterior angles of a polgon - no matter how many sides - is 360 degrees.
