Answer:
Β 1 -(β2)/2 β 0.292893
Step-by-step explanation:
The diagonal length AC is β2, so the distance EC is β2 -1. That is the diagonal of the square whose side length is the length of interest. That side length will be (β2)/2 times the length of EC.
Β shortest distance from E = (β2 -1)(β2)/2 = 1 -(β2)/2
