It seems like you're asking for a matching exercise involving points and their respective approximations of irrational numbers. However, I need the specific irrational numbers and their approximations associated with points A, C, E, and L in order to help you complete the matching.
Could you please provide the approximations for each point? For example, are we looking at approximations of numbers like π (Pi), √2 (the square root of 2), e (Euler's number), etc.?
