Do The bases of a cylinder must be polygons?
A cylinder has circular parallel bases
Must the bases of a cylinder be polygons?
false
What have 2 parallel bases that are not polygons?
There are several cases: any 3 dimensional or more object. Since a polygon is defined as being confined to a single plane, any shape that violates the plane is not a polygon but may still have parallel bases. For cases in only 2 dimensions: Any object that has curves in addition to the parallel bases. A polygon's definition includes only straight sides. Finally, unclosed shapes can have 2 parallel bases with out being polygons even if in a single plane and made up of only straight line sides. A polygon must be closed.
What is important about parallel?
The importance is that parallel lines must never meet.
A Cylinder has how many Bases?
2. One at the top and one at the bottom. The face that is cylindrical cannot be counted as a base because it is curved - in 3D shapes the base must be flat.
