Most of geometry and trig was covered in that algebra textbook. The rest, I picked up more from shop and programming classes than I did from my high school mathematics courses; trig is incredibly useful for e.g. planning out rafter designs for building construction, and when the programming environment you are using for graphics consists primarily of poking pixels, and doing collision tests by hand, you become very familiar with geometric equations. Stats remained something of a blind spot.
