"Anterior" is simply "front". "Ventral" is "down" in this and most other cases: venter = belly. So, the ventral margin of the pmx is the one with the teeth. You hold a ruler to the front side, another along the toothrow, and measure the angle between them.
The character could also be worded as "pmx pointed (0); blunt, rounded (1); rectangular or slightly overhanging (2)", but that wouldn't be precise enough to deal with borderline cases. (In my work I've encountered lots of characters that were worded in such imprecise ways, and lots of borderline cases that were hard to score for such characters.)

I'm pouring over this paper on phylogeny tyrannosauroid dinosaurs. I'm
not understanding what is being measure in the premaxilla bone, which is
a measured characteristic 13. Does anyone have an example of a diagram
of what is being measured?
(Premaxilla orientationa and shape of anterior margin)
I don't know what ventral and anterior margins are and what angle is
being measured.

13) Premaxilla, orientation and shape of anterior margin: smoothly
curved and projection posterodorsally, angle between ventral margin of
premaxilla and anterior margin is less than 90 degrees (0); smoothly
curved and projecting vertically or slightly anterodorsally, angle
between ventral margin of premaxilla and anterior margin is equal to or
greater than 90 degrees (1); projecting vertically or slightly
anterodorsally, with a discrete inflection point between a more vertical
ventral portion and a more horizontal dorsal portion (2). ORDERED
(Brusatte et al. 2010:13).
This character is slightly modified following Brusatte et al.
(2014:485). We have transformed the original character of Brusatte et
al. (2010:13) into an ordered multistate by adding a new intermediate
state referring to an approximately vertical (or slightly anterodorsally
inclined) anterior margin of the ventral portion of the premaxilla.
State 2 now refers to a special condition of this state, in which the
anterior margin is vertical (or anterodorsally inclined) and there is
also a discrete inflection point between the more vertical ventral
portion of the anterior margin and the more horizontal dorsal portion of
the margin. Taxa with this condition, therefore, do not possess a
smoothly curved anterior margin of the premaxilla. Tyrannosauroids are
characterized by either state 1 or state 2, with state 2 referring to a
subset of basal tyrannosauroids (Dilong, Guanlong, Kileskus,
Proceratosaurus, Sinotyrannus).
