In the renaissance Leonardo DaVinci discovered that the perfect square is 1:1:618. I would like to know if there is a perfect square measure, then is there a perfect measure for a triangle or a circle? If so, could Pi be measured by a new and other calculation system which is similar to circumference divided by diameter? Could the perfect triangle match be 1:1:3? Suppose there are constants which could lead to a solution of Pi by another way method, might there be a concept of calculating its infinite system to an including possibility in some kind of mathematical solution for calculation from a different formula to find it?
