I'm going to take a guess. A 2-D object must have at least three sides (a triangle) A 3-D object must have at least four sides (a triangular pyramid) I'm going to guess that a 4-D object must have at least 5 sides, if the pattern holds...
a decagon is a 2-dimmesional object with 10 sides and 10 angles
There is no such thing as an object with two sides.
Isoceles Triangle Thank You & Good Night!

They are called sides.
When an object is not in motion, it is said to be at rest.
All 12 sides are straight! This is a 2 dimensional object. * * * * * A dodecahedron is NOT a 2 dimensional object so the above answer is utter nonsense. A dodecahedron has pentagonal faces.

it is an object that does not have an explanation for the sides
