A triangle labeled with points A (top vertex), B (bottom-left), and C (bottom-right) needs to be connected to a rectangle with points W (top-left), X (top-right), Y (bottom-right), and Z (bottom-left). The instruction is to connect A to Y and B to X. In the assembled shape, which edges are joined?

CONNECTION ASSEMBLY questions require following the given connection instructions precisely to determine how shapes join. KEY PROCESS: (1) READ the connection instruction carefully — A to Y means point A on the triangle connects to point Y on the rectangle; B to X means point B connects to X; (2) LOCATE the labeled points on each shape; (3) The EDGE between two connecting points on the same shape must ALIGN WITH the corresponding edge on the other shape; since A connects to Y and B connects to X, the edge from A to B on the triangle must match the edge from X to Y on the rectangle; (4) The direction of the edge matters — the A end touches the Y end, and the B end touches the X end; (5) ROTATE and FLIP the triangle mentally until its A-to-B edge can align with the Y-to-X edge of the rectangle in the correct orientation. COMMON MISTAKE: Correct identifying which edges connect but placing them in the wrong direction (A at Y's position and B at X's position vs. A at X's position and B at Y's position). The specific labeled connection points must match exactly — swapping them would be an incorrectly assembled configuration even if the overall silhouette looks the same.
