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

No. of No. of

Sides Name Prefix Name Suffix Sides

20 Icosikai... ...henagon 1

30 Triacontakai... ...digon 2

40 Tetracontakai... ...trigon 3

50 Pentacontakai... ...tetragon 4

60 Hexacontakai... ...pentagon 5 70 Heptacontakai... ...hexagon 6

80 Octacontakai... ...heptagon 7

90 Enneacontakai... ...octagon 8

...enneagon 9

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

What are the names of polygons 60-70?

It's quite acceptable to call it a 60-agon or a 70-agon but what's most important is knowing how to work out its properties.


What do you call a 60 sided shape?

A 60 sided shape is called a hexaconta. The hex prefix means 6 and the conta suffix is used for polygons with 20 to 100 sides.


How many sides does a polygon have with the measure of 60 degrees?

It is impossible for a polygon to have only a measure of 60 degrees...if you mean per angle, then it has to be an equilateral triangle...of course we are talking about regular polygons here, right? :)

Which shapes have lines of symmetry which meet at 60 degrees?

Regular hexagons and other shapes based on hexagons. Polygons with 6k sides (positive integer k) where sets of k adjacent sides and angles are congruent to the next set, and other shapes based on these.


What is 7h plus 39 equals 60?

7h+39=60 Take away 39 from both sides (called isolating your variable) 7h=21 Divide by seven, because (I assume) you are looking for h, not 7h h=3 And to check: 7(3)+39=60 21+39=60 60=60


What is 21 percent onto 60?

21 percent onto 60 = 12.621% of 60= 21% * 60= 0.21 * 60= 12.6


What is 21 divided by 60?

0.35


Is a hypotenuse equal to the sides of an equalateral triangle?

Yes. The equilateral triangle will have all sides with the same length. An equilateral triangle will ALSO be a equiangular, with each angle being 60 degrees. This fact does not extend to other polygons. An equilateral quadrilateral is a rhombus, while an equiangular quadrilateral is a square.


What should be added to both sides of this equation to solve for the variableA plus 39 equals -60?

-21


What is 21 times 60?

21 * 60 = 1,260
