AI Drawing Prompt Reference

Draw a circle and a radius from the center to a point on the circle. Then, construct a perpendicular line to the radius at that point, which intersects the circle at the tangent points. Connect the center to each tangent point to form tangent lines. Additionally, draw a circle centered at the center with a radius equal to the distance from the center to the tangent points, and find the intersections of this circle with the original circle to further illustrate the geometric relationships involving tangents and radii.
