/////Bisect and Quadrate (which in my dictionary means a square or rectangle and doesn't mean anything to do with dividing a circle)/////

Bisect simply means to divide into two equal halves. I used quadrate as a verb although it is properly an adjective which means to be square as in 90 degrees. I used it as in "to make square" as in 90 degrees. Your usage of quadrate--a cublical volume or square area--is a noun which I clearly did not use.

Sorry if that boggled your little mind.
