Answer any one question from Q1 and Q2
1 The point M of line MN is in HP while its other end N is 50 mm above HPand 80 mm in front of VP. The line is inclined to VP at an angle of 40°.Draw the projections of a line if its elevation makes 29° with HP. Find true length of line and the inclination made by the line with HP. Also, locate the traces of line.

2 An isosceles triangle, base 50 mm and altitude 80 mm, is resting in VP on its base. Its surface is inclined to VP so that the corner opposite to resting side is 50 mm in front of VP. Draw the projections if its resting side is inclined to HP at an angle of 45°.Find inclinations made by the plane withHP and VP.
