In case you are referring to the first law,to some extent yes it is imaginary because a plane is a human made concept ( does not have any physical existence) but it is nevertheless important.
WebProposition 47. In right-angled triangles the square on the side opposite the right angle equals the sum of the squares on the sides containing the right angle. Let ABC be a right-angled triangle having the angle BAC right. I say that the square on BC equals the sum of the squares on BA and AC. I.46. I.31, I.Post.1. WebEuclid number.
