Move a plane in 3D by a certain degree

Hello all, Assume that we got a rectangular plane with four corners having coordinates of (1,1,4), (1,3,4), (3,1,4) and (3,3,4). So, it is placed 4 meters above the ground. the centre of this plan has 90 degree elevation angle. If I want to tilt the plane by 30 degree, the corners coordinates will accordingly change. the question how to calculate their images in the new plan position. Also, if I want to find an image of any spot (say the spot is (2,2,4))) within the plane how to calculate that? thanks in advance
