Section 3 describes the territory forming Telangana; Section 4 says the successor State of Andhra Pradesh comprises the rest of the existing state. In the original setting, Telangana's listed districts were not a description of today's district layout. Both successor States have since been able to alter internal districts. Section 11 preserves their power to change district names, areas and boundaries after the appointed day. Thus the 2014 state boundary and a 2026 district map belong to different administrative scales.

The map in this book marks the two successor States and the 2014 transition. Do not transfer a 2014 district-level fact into a 2026 map without reaggregation. One special territorial issue was the project-affected area around Polavaram. The 2014 amendment and later administrative actions addressed certain transferred territories. A question about a specific village requires the amending text or official notification, not only the main state outline. For standard SI/Constable recall, Sections 3 and 4 establish the split, and Section 11 explains why later district change is possible.

Worked example: A 2014 district list and a current 28-district AP map appear together. Section 3 defines Telangana's territory at reorganisation; Section 4 defines the remaining AP territory. Section 11 allows successor States to alter their internal districts. Thus a new district does not itself redraw the interstate boundary. For a transferred village near Polavaram, however, inspect the specific amending law or notification rather than guessing from a state silhouette.

Active recall: Which section forms Telangana and which defines residuary AP? Why can a state boundary stay fixed while district counts change?
