Topics in Figure Formation & Analysis
1
Type I: Formation of Geometric Figures (Triangle / Square / Rectangle)
- A set of 4–6 irregular piece-figures is given; you must identify which three (or more) pieces, when assembled without overlapping or gaps, form a complete geometric shape such as a triangle, square, o
- Start by identifying the piece that contains a definitive geometric feature — for example, a right-angle corner for a square, or a sharp apex for a triangle — as your anchor piece.
- Each piece is like a puzzle fragment: the curved or slanted edges of one piece must perfectly interlock with the complementary edges of another piece.

Type II: Making Up a Figure from Given Components
- A box 'X' contains multiple geometric pieces (triangles, quadrilaterals, irregular polygons); you must identify which answer option (a composite figure) can be constructed using all pieces from X with
- All pieces in box X must be used — if an answer option leaves any piece from X surplus, it is incorrect.
- Pieces cannot overlap; they can only be placed edge-to-edge or vertex-to-vertex within the boundary of the composite figure.

Type III: Paper Folding to Make 3D Figures (Net Analysis)
- A flat 2D net (unfolded surface) is given; you must determine which 3D solid (cube, cuboid, pyramid, prism, etc.) it forms when folded along the crease lines.
- Alternatively, a 3D figure 'X' is shown and you must identify which among the four nets, when folded, produces exactly that figure.
- Each face of the 3D solid corresponds to exactly one polygon (usually a square, rectangle, or triangle) in the net — identify and count them.

Type IV: Rearrangement of Parts of a Given Figure
- A key figure 'X' is divided (explicitly or implicitly) into parts; the answer options show different rearrangements of those same parts — you must identify the correct rearrangement.
- The total area is conserved: the rearranged figure has the same area as the key figure, even if its overall shape appears different.
- Parts may be translated (moved), rotated, or reflected in valid rearrangements; they cannot be scaled (resized).
