Given below are five figures marked A, B, C, D and E. Select the option where when three of the given figures are fitted together, they will form a complete Triangle?

Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → BCD
Pieces B, C and D fit together to form the complete triangle, as shown below: B makes the top, C fills the notch under B, and D, turned over, completes the bottom-right corner.

In the completed triangle the pieces are drawn to their exact shapes; the pieces printed in the paper are rough sketches of the same shapes, drawn at different sizes and slants.
