SOLUTION
The diagram above satifies all the properties of a parallologram
Which are
[tex]\begin{gathered} \text{opposite angle are equal} \\ \text{Opposite sides are equal and parallel} \\ \text{adjacent angle are supplementary} \end{gathered}[/tex]But if from the rule of isoseleses triagle we can conclude that all the side of the figure above are equal
Hence the most specific description for GEFH is
[tex]\text{Rhombus}[/tex]
