A rhombus
Any regular polugon with 5 or more sides. Many irregular polygons with 5 or more sides will also meet the requirements.
The name of a 69-sided polygon would be derived from the prefix for 60 when used in the concept of regular polygons (hexacontakai) and the prefix for 9 (ennea), with the suffix -gon at the end of the word. Therefore a 69-sided polygon would be called a hexacontakaienneagon.
