AI Drawing Prompt Reference

Draw an angle by first creating a circle and marking a point on it. Then, draw a vector from the center to this point. Next, create two circles with different radii, mark points on each, and draw vectors from the centers to these points. Measure the angle between the two vectors and draw the sides of the angle. Draw an auxiliary circle intersecting the coordinate axes to get four points, and connect these points with line segments. Finally, create a sector with the center as the vertex and the two vectors as boundaries, then combine the sector with the two line segments to form a quadrilateral.
