Coordinate Geometry

What is coordinate geometry?


Coordinate Geometry is the study of geometry using a coordinate system




What is the equation of a circle?


Possible questions inculde: finding radius - use the equation (x-h)² + (y-k)² = r finding diameter - find radius and multiply by 2 finding the x or y coordinate of an endpoint - use the equation (x-h)² + (y-k)² = r finding the center of the circle, when the endpoints of the diameter are given - use the midpoint formula midpoint formula =
