2D is a decagon.
3D is a decahydron.
A 10 sided polygon is a decagon.
Not sure about "another" since there is no such thing as a dectagon. A 10 sided figure is a decagon.
Septagon
The name of a 12 sided polygon is Dodecagon.
A 10 sided figure
For easier use, mathematicians usually use the number of sides and add -gon to the end of it. In other words, a 175-sided figure would be called a 175-gon for casual use.When using traditional Greek terminology (such as hexagonfor a six-sided figure), a 175-sided figure would be called a hectakaiheptacontapentagon.
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. )
