Rohit realises that square is both a rhombus and a rectangle. He is at what stage of Van Hiele's visual thinking?

Van Hiele's levels of geometric thinking are: Level 0 (Visualization/Recognition) — identifying shapes by appearance; Level 1 (Analysis) — recognizing properties of shapes; Level 2 (Informal Deduction/Relationships) — understanding relationships between properties and between shapes; Level 3 (Deduction) — formal proofs; Level 4 (Rigor) — comparing axiomatic systems. Recognizing that a square is both a rhombus and a rectangle requires understanding class inclusion relationships between quadrilaterals, which is Level 2 thinking.
