Question

Which of the following is not a 3-D shape?

• A. Square
• B. Triangle
• C. Circle
• D. All of the above.

Answer 1

The correct option is D All of the above.

As square, triangle and circle are 2-D shapes which just have length and breadth. A 3D shape must have 3 dimensions (length, breadth and height). So, none of them is a 3D shape.
