At least one, usually two.
a polygon has all closed sides and no curved sides
a trapezoid has no curved faces it is all straight faces
No, because all quadrilaterals have 4 straight sides.
no, because the main charcteristic of a square is that all the sides are equal. If there was a curved side, it would be a polygon, not a square.
A curved side, a non-coplanar side (ie all sides must be in the same plane), less than 3 sides.
No. Example: A cube has no curved sides. A cylinder has curved sides but not all shapes with curved faces begin with c.
a polygon has all closed sides and no curved sides
All sides are connected and there are no curved sides.
none! If it is a square, then all of the sides are straight...
All shapes have sides. Including a circle which has one curved side.
a trapezoid has no curved faces it is all straight faces
No, because all quadrilaterals have 4 straight sides.
the answer is convex lens! to find this out you should know that concave lens are curved outward and convex lens are curved inward! i hope this helped and if it didn't i would like to apologize for not answering your question, now i bid a fine fairwell to all!
No, all polygons have straight lines. All lines are straight
no, because the main charcteristic of a square is that all the sides are equal. If there was a curved side, it would be a polygon, not a square.
There is no difference between lense and lens. All is the same.
You could say they all consist of angles, never curved, and all have 4 sides...
