### Answer any one question from Q1 and Q2

1 The TV of a 80 mm long line AB measures 50 mm. The point A is 50 mm in front of VP and 20 mm above HP. The point B is 20 mm in front of VP and is above HP. Draw the projection of line AB and find its inclination with the HP and VP also locate its traces.(12 marks) 2 A thin rectangular plate of size 70 mm × 40 mm appears as a square of side 40 mm in TV with one of its side inclined at 30° to VP and parallel to HP. Draw the projection of the plate and determine its inclination with HP.(12 marks)

### Answer any one question from Q3 and Q4

3 A pentagonal prism of base 30 mm side and axis 60 mm long is resting on a corner of its base on HP with a longer edge containing that corner inclined at 45° to the HP and vertical plane containing that edge and axis inclined at 30° to the VP. Draw its projection.(13 marks) 4 (a) Draw an involute of a circle of 50 mm diameter.(7 marks) 4 (b) A right circular cone of a base diameter 50 mm and axis height 60 mm has its base on HP. Draw the development of lateral surface of cone.(6 marks)
