A WRIGGLE.
No. It is close with four sides and four interior angles each 90 degrees.
an open plan figure is a figure whose end point are not connected
It depends when the windows are open no, but when they are not, yes.
Polygons by definition are closed: when all the sides are connected and there are no open spaces between them.
A WRIGGLE.
All sides are connected with no open gaps, sides do not intersect or cross over each other.
To answer your question first here is the definition of polygon "a closed plane figure bounded by straight sides " So it makes no sense to count the sides in an open polygon since it is really not a polygon.
No. It is close with four sides and four interior angles each 90 degrees.

an open figure is a figure with its ends NOT connected
an open figure is a polygon that is not completely closed.
an open plan figure is a figure whose end point are not connected
most polygons have 4 sides but they can also have 3 sides non polygons can have 8 9 or 12 sides The above answer is total rubbish. The following is mostly correct except that a polygon must have straight sides so you cannot have a polygon with two sides. Answer: a polygon is a closed figure having any number of sides more than one. (poly=many) A polygon with 3 sides is a triangle. A polygon with four sides might be a square, rhombus, rectangle or something completely irregular. Angles do not have to be right angles. A figure that is not enclosed ( a squiggle, a semicircle, any open figure) is not a polygon.
It depends when the windows are open no, but when they are not, yes.
closed figure
Polygons by definition are closed: when all the sides are connected and there are no open spaces between them.
