Not sure about "another" since there is no such thing as a dectagon. A 10 sided figure is a decagon.
If a dectagon is another word for a decagon then this is a 10 sided polygon. No matter how many sides it has, the sum of the external angles of a convex or regular polygon is 360°.
A 10 sided polygon is a decagon.
The name of a 18 sided figure is an octadecagon or octakaidecagon. As you can see the prefix octa- means 8, and deca- means 10. It has 18 sides and 18 vertices,
decagon.dec/dek means ten ( dekameter = 10 meters)
A plain sided, 2-dimensional figure of TEN(10) sides. NB From the Latin roots, then names of polygons are :- 3 = tri 4 = tetra/quad 5 = pent 6 = hexa 7 = hepta 8 =- octa 9 = nona 10 = deca (As in decagon above).

Decagon.
A 10 sided polygon is a decagon.
A 10 sided figure
they're not. A 10 sided figure is a decagon, while a 12 sided figure is a dodecagon. do=2, deca=10.
You only know that all ten interior angles of a 10-sided figure add up to 1,440 degrees.IF the 10-sided figure happens to be REGULAR, then each of them is 144 degrees.
A ten sided figure is called a Decagon. ( i think that's how you spell it. )
