Question 1: Which fits better - a round peg in a square hole or a square peg in a round hole?
Question 2: Consider pairing regular polygonal shapes, other than a square, with the round peg and round hole. (Ex: An equilateral triangular peg and hole with a round peg and hole or a regular pentagonal peg and hole with a round peg and hole). Do you always get the same results as in the original question??
Any help is much appreciated!
