About the Lesson
In this activity, students explore the general equation of a circle with centre (h, k) and radius r. For the first part of the activity, students adjust the radius of the circle and drag a point around the circle to capture the coordinates. In the second part of the activity, students translate the circle using sliders for h and k to view how the equation changes.
