Why is squaring the circle impossible with ruler and compass?
AA square has four sides
BPi is a rational number
CA circle has no corners
DPi is a transcendental number
Answer & Solution
Correct answer: D. Pi is a transcendental number
1. Lindemann showed in 1882 that pi is transcendental.
2. A square of equal area would need a length involving pi, which constructions cannot produce.
3. The shape of the square or circle is not the reason; the number pi is.
