Geometry is the poor stepchild of the Math sequence continually being shorted in favor of more Algebra or Statistics.
If you look at a typical sequence nowadays its heavy on definitions/taxonomy, trig, analytic i.e. Cartesian geometry at the expense of classic Euclidean topics.
Example From the CC standards: (this curriculum will tend to do proofs during only parts of a few units for the entire year)
