How do you make a w made of 4 pens into a perfect square by only moving one pen
The correct answer and explanation is:
To turn a “W” made of 4 pens into a perfect square by moving only one pen, here is the correct answer:
✅ Move the middle pen (the one forming the center point of the “W”) and place it across the top of the W to form a square.
📖 Explanation (300 words):
At first glance, the challenge seems paradoxical. A “W” made from 4 pens is typically arranged like this:
\ /\
\/ /
Imagine each pen forming one of the strokes in the letter W. That is:
- The first pen leans down-right (
\), - The second leans up-right (
/), - The third leans down-left (
\), - And the fourth leans up-left (
/).
The pens are arranged so that the endpoints meet at two bottom and one middle point, forming a “W” shape.
The key to solving this puzzle lies in rethinking the geometry. Rather than focusing on the letter W literally, consider the shape it creates and how pens are connected.
Here’s how to solve it:
- Identify the pen that forms the central dip of the “W” — this is the middle connecting pen.
- Remove that pen carefully.
- Place it horizontally on the top, connecting the outer two vertical strokes.
This forms a square with:
- Two vertical pens as the left and right sides.
- The two other pens forming the bottom and top sides.
Why it works:
A square has four equal sides and four right angles. By repositioning just one pen and assuming all pens are of equal length, placing it horizontally across the top completes a quadrilateral with four equal sides and right angles — a perfect square.
This puzzle tests spatial reasoning, creative thinking, and the ability to think beyond initial impressions. Many people focus on the “W” and try to rotate pens within the shape, but the correct move is actually removing the complexity by simplifying the form.
