problem 2: A line AB 65 mm long has its end A 20 mm above HP and 25 mm in front of the VP. End B is 40 mm above HP and 65 mm in front of VP. Draw the projections of the line. Find out its true and apparent inclinations with HP and VP.

problem 3: The projections of a line measures 80 mm and in the top view and 70 mm in front view. The mid-point of the line is 45 mm in front of VP and 35 mm above HP. One end is 10 mm in front of the VP and nearer to it. Draw the projections. Find out the true length and true inclinations with reference planes.

problem 4: The top view of a line CD has a length of 80 mm and makes 30o with horizontal. The end C is in VP and 52 mm above HP. The end D is in HP. Draw the projections of line. Find out the true length and true inclinations with HP and VP. Mark its traces on two planes.

problem 5: A line CD inclined at 25o to HP measure 80 mm in top view. End C is in the first quadrant and 25 mm and 15 mm from HP and VP correspondingly. End is at equivalent distances from both reference planes. Draw its projections; find out true length and true inclinations with VP. Place the traces.
