AI Drawing Prompt Reference

Draw a unit circle and demonstrate similarity transformations. Start by drawing the intersection point A of the x-axis and y-axis, then draw the unit circle c with A and B as its center. Next, draw vector u from A to B, and draw perpendicular lines a and b from B to the x-axis and y-axis, respectively, with their intersection points being C and D. Then, draw vector v from C to B and w from D to B. Continue by drawing two points E and F on the unit circle c, and then two points G and H on the x-axis. Next, draw two points I and J on the unit circle c, and then two points K and L on the y-axis. Continue by drawing two points M and N on the unit circle c, and then two points O and P on the x-axis. Next, draw two points Q and R on the unit circle c, and then two points S and T on the y-axis. Then, draw two points U and V on the unit circle c, and then two points W and Z on the x-axis. Finally, draw two points A_1 and B_1 on the unit circle c.
