Q2. A line is placed in 1st angle of projection whose one point is at a distance of 20 mm above the H.P. and the projection of line makes an angle of 60 with H.P in front view. The same point maintains a distance of 30 mm from the V.P. and the projection of line makes an angle of 45 with V.P. in top view. Second Point is placed at the distance of 50 mm above the H.P. Determine the True Length of the line by using: - (a) Rotation Method. (b) Auxiliary Method.
