10.2 Circles
"Use and determine the standard forms of the equations
of a circle."
NCSCOC 1.02, "Use quadratic relations to model and solve
problems."
WIMD: What I must do:
• I will determine the standard form of the equation of a circle given the location of the center and a given radius.
• I will determine the general form of the equation of a circle given three points on the circle.
• I will use Completing the Square to derive the standard form from the general form of the equation of a circle.
