Circle Equation by kokila
Loading the math board and drawing, please wait…
This example demonstrates how to draw a circle given its center and radius and derive its equation. Core math concepts include the standard equation of a circle, coordinate geometry, and geometric construction. Construction highlights: uses Polygon and Circle commands, and objects like radius, A, poly1, a, b, d, e, ch, f, ck, h, text1, text2. Suitable for high school students learning coordinate geometry or for educational demonstrations.

Polygon(Corner[1], (Corner[1] + (0.7 * Corner[2])) / 1.7, (Corner[4] + (0.7 * Corner[3])) / 1.7, Corner[4]) → poly1, a, b, d, eCircle(A, radius) → fCircle(A, radius) → h
AI Drawing Prompt Reference
Draw a circle with a given center and radius, and show how to derive its standard equation. First, create a polygon connecting the center to a point on the circle, then draw a circle centered at the same point with the radius. Label the center and radius, and write the standard equation of the circle beside the diagram.
The prompt above was compiled from the original drawing commands and is for reference only.
