HEPTAGON i know it sounds wierd but that's what its called.
A decagon.
A shape with four sides and three vertices does not exist in Euclidean geometry. In Euclidean geometry, a shape must have the same number of sides as vertices. Therefore, a shape with four sides would have four vertices.
It means 7 as in an heptagon which has 7 sides

7 sides heptagon 9 sides nonagon
