There are a number of polygons that are similar to it but if you mean things that look like decagons than nonagon, undecagon, dodecagon, and octagon.
An undecagon has 11 sides.
An undecagon, which has 11 sides, cannot tessellate by itself because its interior angles do not allow for the angles to fit together without gaps or overlaps. The interior angle of a regular undecagon is approximately 147.27 degrees, and since it does not divide evenly into 360 degrees, it cannot be used to tile a plane on its own. However, it is possible to create a tessellation using a combination of undecagons and other shapes that fill the gaps.
An undecagon is a polygon with 11 sides. The formula to calculate the number of diagonals in a polygon is given by ( \frac{n(n-3)}{2} ), where ( n ) is the number of sides. For an undecagon, this becomes ( \frac{11(11-3)}{2} = \frac{11 \times 8}{2} = 44 ). Therefore, an undecagon has 44 diagonals.

a shape with eleven sides is called a undecagon
