Co-ordinate Geometry in the xy plane

Co-ordinate Geometry in the xy plane involves knowing about:

Understand and use the equation of a straight line in various forms including the gradient conditions for parallel and perpendicular lines. Be able to use these in a range of contexts;

Understand and use the coordinate geometry of a circle using the equation of a circle, completing the square to find the centre and radius and make use of circle theorems;

Understand and use parametric equations of curves and be able to between the Cartesian and parametric forms;

Use parametric equations in modelling in a variety of contexts.
