Drawing a circle with a dot without lifting the pen is not an easy task at first glance. At the same time, the lack of accuracy of the wording gives the right to the existence of several solutions to this puzzle.
Instructions
Step 1
One of these options is to position the point directly on the circle line. Take a blank sheet of paper and a pen. Draw a dot. It is from this point that you begin to draw a circle. Finish drawing the circle at this point. It turns out that the point will be located directly on the line of the circle. So purely formally, you can solve this problem.
Step 2
To draw a circle with a dot, draw an almost filled shape. Draw a circle on a blank piece of paper, without lifting the pens from the surface, and immediately start painting over the entire inner area of the circle. Put a bold point anywhere without lifting the handles. After that, continue (also without removing the rod from the surface of the paper) paint over the circle. The point will be located inside the filled circle. This is another option for solving the problem.
Step 3
Since this logical problem lacks clarification about the use of the second pen, as well as about how many writing utensils can be used in the drawing process, draw a point inside the circle with one pen, do not tear it off the surface of the paper. Draw a circle with another pen, also without lifting it off the surface of the paper.
Step 4
There is one more way to solve this issue. Since there are no additional conditions, you can draw a circle connected by a line to a point located inside. To do this, first draw a circle, then, without lifting the handles from the surface of the paper, draw a line towards the center of the circle. Without drawing the line outside the circle, and also without lifting the pen from the surface of the paper, put a point at the end of this line. You can also draw a point outside the circle (the condition does not indicate whether the point should be located inside or outside the circle). To do this, use the same algorithm of actions, but direct the line outward, and not inside the circle.
Step 5
To solve this problem in a non-standard way, draw a circle, and then fold the corner of the paper where the handle is located. Do not tear it off from the surface of the sheet. Do this so that the shaft of the pen touches the back of the paper in the center of the circle you have drawn. Then pierce the paper at this point. So the problem will be solved.
