Q.2) The horizontal line h in space placed in position that the coordinates of its two ends are D(5,5,2) and E(?,?,?). If the point E is located on the straight line m[A(1,3,1),B(6,2,3)], draw the two projections of of the horizontal line h. Q.3) Assign the two projections of straight-line K [A(4,-4,2),B(-2,1,Z)], whose true length is 9 centimeters, then set its trace and the penetrate angles of the straight-line in space, as well as set the angles of inclination at the horizontal and vertical plane, knowing that ZA
