AI Drawing Prompt Reference

Draw a dynamic diagram of two rolling carts, including two circles and two line segments, and a triangle. First, draw a circle centered at Q with radius a_5, and another circle centered at B with radius 39 minus the length of segment BA. Then, draw a line segment connecting Q and B, and another line segment connecting B and A. Next, draw a line segment connecting A and A_2, and line segments connecting Q and A, and Q and A_2. Construct two triangles, one with vertices A_2, Q, and B, and another with vertices Q, A, and B. Finally, draw two rays from A and D, and from A_2 and E, and label the angle BQA_2.
