Au contraire:

An inverted V is a reasonable description of the antenna that is
based on a dipole.  Calling it a " half-Rhombic turned on its side"
is not only more clumsy to say it is also technically incorrect.
The rhombic has legs that are MULTIPLE 1/4 Wavelengths on
a side (when used in the resonant mode without a termination), 
whereas the inverted V has only a SINGLE 1/4 wave on a side.
In the non-resonant mode the rhombic still has legs MUCH longer
that a 1/4 wavelength and requires terminations--something that is
never done with an inverted V.
