They are all regular shapes like a circle but with straight sides all the same length and all angles the same in each shape: nonagon - 9 sides octagon - 8 sides heptagon - 7 sides pentagon - 5 sides and missing from the list is hexagon - 6 sides.

Hexagon, heptagon, octagon, nonagon all have more sides than a pentagon

A pentagon (5-sides), hexagon (6-sides), heptagon (7-sides), and octagon (8-sides) are all examples of shapes with more than four straight sides.

Have you asked the fighters in the Octagon or the Pentagon? Or did someone put a "Hex" on your thinking stop sign? Best I can tell, all regular polygons have the same number of sides and interior angles

I am a rhombus or an equillateral triangle, pentagon, hexagon, octagon etc.

yes a pentagon is one of the polygons and it has 5 sides and a polygon can be made with all sides straight and they have to be all in a closed shape if it has a little bit of open space it is not a polygon polygons: Quadrilateral 4 sides Pentagon 5 sides Hexagon 6 sides Octagon 8 sides hepatgon 7 sides Nonagon 9 sides Decagon 10 sides hope my answer is useful!

All sides of an octagon are parallel to one other side. There are 4 sets of parallel sides.

it has 5 sides A pentagon has five sides. "Regular" means that they are all the same length. A pentagon has 5 sides. 5 There are 5 sides in a regular pentagon a plane figure with five sides and angles There are 5 sides 5 5 sides

Not necessarily. If all sides are the same size, and all angles are also the same, then it is called a "regular octagon". But an irregular octagon is still an octagon - the only requirement is that it have 8 sides.

There are 74 sides in all.
