What is a 11 and 12 sided figure called?
dodecagon
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.

What is a 12 sided 3d shape called?
In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” + ἕδρα hédra “base”, “seat” or “face”) or duodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid.

What do you call a 13 sided polygon?
After about 6 sides mathematicians usually refer to these polygons as n-gons. So your 13 sided polygon I would call a 13-gon.

How are the sides of a polygon joined?
Their sides are simply joined by straight lines. Another thing to note is that polygons do not have holes, nor do they intersect with themselves. As for the number of sides, they could go on for infinity. When you think of a polygon, you may think of basic shapes you may have learned of in school.
Do you have all angles equal in a polygon?
A regular polygon has all angles equal and all sides equal, otherwise it is irregular
