### Answer any one question from Q1 and Q2

1 The point A of line AB is in HP and 20 mm in front of VP. The front view and top view of line makes 40° and 45° with HP and VP respectively. Draw the projections if the projector distance between end points of the line is 70 mm. Find true length and true inclinations. Also, locate the traces of line.(12 marks) 2 A pentagonal plate of side 40 mm, is resting in HP on its side. Then its surface makes 40° with HP. Draw the projections if its resting side is inclined to VP at an angle of 45°. Find inclination made by the plane with VP(12 marks)
