CircleCoordinate GeometryGeometric Construction
This example demonstrates how the center and radius of a circle determine its equation. Key mathematical concepts include the equation of a circle and coordinate geometry. Using GeoGebra commands such as Point, Segment, and Circle, you can dynamically change the center and radius to observe how the equation changes. Suitable for students in middle school and above to learn about the equation and geometric meaning of a circle.

GeoGebra Commands & Parameters

  1. Point(Circle[A, abs(Radius)]) → B
  2. Segment(A, B) → a
  3. Circle(A, B) → c

AI Drawing Prompt Reference

Draw a circle with center A and radius equal to the length of AB. First, create point A on the coordinate plane, then create point B by rotating A 90 degrees around itself, which gives the length of AB as the radius. Next, create a segment AB, and finally, draw a circle with A as the center and AB as the radius.
The prompt above was compiled from the original drawing commands and is for reference only.
