A nonagon has nine sides and a pentagon has five, so four more sides....
Because shapes with parallel sides are weak. Triangular sides are more stable - which is why the steel infrastructure in buildings and bridges etc usually have triangular cross-members to add strength to the structure.
a hexagon * * * * * or any one of infinitely many polygons with 5 or more sides; any one of an infinite number of polyhedra with more than 4 faces, as well as other shapes that do not fit into these classifications: for example, a closed plane shape with five curved sides which meet pairwise.
Acute triangles. They can have three angles, all less than 90 degrees (total is 180 degrees).Shapes with more than three sides must have angles of 90 degrees or more because the total of their angles must be 360 degrees (quadrilaterals) or more.
There two different shapes that have more than one vertex. One is a triangle it is a plane figure that has three straight sides and three angles and a quadrilateral which a four sided figure.
Most shapes will have more than two sides. If the sides are straight lines, the shapes MUST have more than two sides.
There is no special name that distinguishes shapes with more than four sides from shapes with four or fewer.
Shapes having less than 4 sides or more than 4 sides are not parallelograms
There is no specific term that distinguished between shapes with more than 11 sides from those with up to 11 sides.
There is no special name to distinguish shapes with more than 14 sides from those with 14 or fewer.
There is no special name: they are polygons, as are shapes with 3 or 3 million sides.
Hexagon, heptagon, octagon, nonagon all have more sides than a pentagon
definitely a pentagon can.. It can be any shapes that have more than 4 sides except that they can't be regular shapes.

Any polygon with more than 4 sides.
well... theres a decagon(10 sides)...
