Yes, all rectangles are quadrilaterals because they have four sides and all quadrilaterals have four sides.
It belongs in the class of quadrilaterals that all have 4 sides
All octagons have 8 sides and 8 angles
It would be 60 sides total. You get this from this equation: 5*(4 sides in a quadrilateral)+ 5*(8 sides in an octogon)= 5*4 + 5*8= 20+40 = 60 sides total / in all
Anything without four sides, since a quadrilateral is a polygon with all four sides. An example of a shape not a quadrilateral would be a triangle.
