You can either call them by n-gon for n sides (i.e. 21-gon) or combine a prefix and suffix (i.e. Icosikaihenagon).

What are the names and number of sides of all the polygons?
3 sides= triangle 4 sides= quadrilateral 5 sides= pentagon 6 sides= hexagon 7 sides= heptagon 8 sides= octagon 9 sides= nonagon 10 sides= decagon 11 sides= hendecagon 12 sides= dodecagon 13 sides= tridecagon/13-gon 14 sides= tetradecagon/14-gon 15 sides= pentadecagon/15-gon 16 sides= hexadecagon/16-gon 17 sides= heptadecagon/17-gon 18 sides= octadecagon/18-gon 19 sides= enneadecagon/19-gon 20 sides= icosagon/20-gon 30 sides= triacontagon/30-gon 40 sides= tetracontagon/40-gon 50 sides= pentacontagon/50-gon 60 sides= hexacontagon/60-gon 70 sides= heptacontagon/70-gon 80 sides= octcontagon/80-gon 90 sides= nonacontagon/90-gon 100 sides= hectagon/100-gon 1,000 sides= chiliagon/1,000-gon 10,000 sides= myriagon/10,000-gon 100,000 sides= decimyriagon/100,000-gon 1,000,000 sides= hecatommyriagon/1,000,000-gon Since there are infinitely many polygons, it is impossible to list the names of all of them.
If a regular polygon has exterior angles that measure 60 degrees how many sides does the polygon have?
Exterior angle 60 therefore interior angle at that point 180 - 60 = 120 Figure is a hexagon (Internal angles = 12 - 4 right angles or 720 degrees) ?All polygons have exterior angles that sum to 360 degrees. An exterior angle of a polygon is found by "extending" one of the sides and measuring the angle between that extension and the "next" side. As the polygon in question is regular and has exterior angles of 60 degrees, it has 360/60 sides, or 6 sides.
If a regular polygon has exterior angles that measure 60 each how many sides does the polygon have?
It has 360/60 = 6 sides
How many sides does a regular polygon have if the exterior angle measures 60?
A regular polygon that has an exterior angle of 60 degrees = 360/60 = 6 sides and it is an hexagon
If a regular polygon has exterior angles that measure 60 degree each how many sides does the polygon have?
It has 360/60 = 6 sides
