|This is the first entry of the “Infinity Series”, which will introduce you to the peculiar world of infinity. Today, we will be talking about something with finite area but with infinite perimeter. That sounds odd and impossible but I’ll show you how it can be done.|
Draw a circle and an equilateral triangle inside it, with the three vertices of the triangle touching the circle.
Since we know that the circle has a finite area, the triangle inside must have finite area as well. At this point, we still have finite perimeter on the triangle as well.
Now, divide each edge of the triangle into thirds; draw an equilateral triangle using the middle piece of the divided edges as the base, as follows:
With careful observation, you can see that the perimeter has increased. Specifically, the perimeter increased by a third: instead of one…
