Q.04  A point 'P' is 15 mm above the HP and 20 mm in front of VP and point 'Q' is 25 mm behind the VP and 40 mm below the HP .Draw the projections of P and Q , Keeping the distance between the projectors =90 mm draw straight line joining

1. Their top views
2. Their front views

Q.05  Two points A and B are in the HP the point A is 30 mm in front of VP, where as B is behind VP.

the distance between this projection = 75 mm and the line joining this top views an angle of 45 degree with 'XY' . Find the distance of point 'B' from VP.

Q.06  State the co- ordinate in which the following points are situated.

1. A point 'P' its top views is 40 mm above 'XY' , in front view 20 mm below top view.
2. A point'Q' its projections consider with each other 40 mm below 'XY'.
