STANDARD G.GPE.A.1
GEO/AII
a Derive the equation of a circle of given center and
radius using the Pythagorean Theorem. Find the center and radius
of a circle, given the equation of the circle.
• Finding the center and radius may involve completing the
square. The completing the square expectation for Geometry follows
Algebra I: leading coefficients will be 1 (after possible removal of
GCF) and the coefficients of the linear terms will be even.
• Completing the square may yield a fractional radius.
b Graph circles given their equation. For circles being
graphed, the center will be an ordered pair of integers and the
radius will be a positive integer. |
