Select the figures which, when fitted with each other, will form a complete square.

(A), (B) and (C) only

The correct answer is Option (2) → (A), (B) and (C) only

• To form a complete square, the selected pieces together must provide:

  • Four right angles, and

  • Straight outer edges that can align to make the square’s boundary.

• Figure (A) and Figure (C) together compensate for each other’s slanted edges.

• Figure (B) provides the required right angles and straight sides.

• Figure (D) has an irregular projection that prevents the formation of a perfect square boundary.

Hence, the figures that can be fitted together to form a complete square are (A), (B), and (C).
