AI Drawing Prompt Reference

Draw a geometric diagram to visualize fraction multiplication, featuring a circle and two perpendicular lines. Start by drawing a vertical line from the circle's center to the x-axis, then draw a vertical line from the intersection point to the center, creating two intersection points. Next, draw a circle centered at the origin, intersecting the vertical lines at four points. Form a quadrilateral using these four points and one intersection point. Then, draw a circle on one side of the quadrilateral, intersecting it at two points. Repeat this process with these points to create more nested quadrilaterals and circles, illustrating the concept of fraction multiplication.
