Circle Graphs

In this lesson, we will learn how to draw and recognise circle graphs of the form x² + y² = r² where r is the radius of the circle.

In this lesson, we will use substitution to decide whether a point lies outside or inside a circle.

In this lesson will will investigate the intersection of a line and a circle.

In this lesson, we will earn how to find the equation of a tangent to a circle at a given point.
