How many corners are in a triangle and in a circle

I believe that a similar quesiton was asked by the Greeks, and that was how pi was derived. You can derive pi by drawing a circle of diameter 1, then first inscribe a triangle (3 sides) in it. You could then draw a square (4 sides), pentagon (5 sides), or an n-gon (n sides). Then take the limit as n approaches infinity and find its perimeter (forget what the formula is to find the perimeter of an n-gon) and use the definition circumference=pi*d to find pi (circumference is the perimeter of the n-gon, d is 1).

3 corners in a triangle

0 corners in a circle (It's all curves)
