Coordinate Geometry

Distance, midpoint, and slope; equations of lines and circles; proofs with coordinates — the course capstone.

Builds on

Everything — the Pythagorean theorem (Unit 8), similarity (Unit 7), rotations (Unit 12), circles (Unit 9), and two-column proof (Unit 2), on the Grade-6 coordinate plane.
