AI Drawing Prompt Reference

Draw two parallel lines in the coordinate plane to demonstrate their relationships. Start by rotating a point to create an angle, then use this angle to draw rays and lines. Find the intersections of the lines and use these points to draw circles, triangles, and sectors. Finally, apply dilation and translation to show the transformation of parallel lines and vectors, creating a dynamic geometric illustration.
