Answer 1

$11$ and $12$ sided shape:

• $11$-Sided shape: Any polygon of $11$ sides is known as hendecagon or Unidecagon. It has $11$ sides and $11$ vertices. The measurements of interior angle of hendecagon is $147.27°$ and exterior angle measure is $32.73°$.

• $12$ -Sided shape: Any polygon of $12$ sides is known as Dodecagon. It has $12$ sides and $12$ vertices. The measurements of interior angle of Dodecagon and Dodecagon. is $150°$ and exterior angle measure is $30°$.

Thus, $11$ and $12$ sided shapes are hendecagon Dodecagon.
