Geometry practice, unit by unit

Geometry is where you learn to reason about shapes, not just compute with them. The parts AP leans on most are right triangle trigonometry, radians and circles, and points and lines on the coordinate plane. Those are worth getting comfortable with now.

7 units, 84 questions. Each one has a short worked solution behind "Show me how".
