(b) A line AB 90 mm long is inclined at 30˚ to the HP. Its end A is 12 mm the HP and 20 mm in front of VP. Its front view measures 65 mm. Draw the top view of AB, and determine its inclinations with the VP and also HT and VT. (c) Three vertical poles AB, CD and EF are respectively 5, 8 and 12 meter long. Their ends are on the ground and lie at the corners of an equilateral triangle at 10 meters long side. Determine graphically the distance between the top ends of poles viz AC, CE and EA. (d) Two lines AB and AC make an angle of 120˚ between them in this front view and top view. AB is parallel to both the HPand VP. Determine the real angle between AB and AC. 3. (a) Show by of traces, each of the following planes: (i) Perpendicular to HP and inclined at 30˚ to VP. (ii) Parallel to and 40 mm away from the VP (b) Draw the projections of a regular pentagon of 40 mm side, having its surface inclined at 30˚ to the HP and a side in the HP and inclined at an of 60˚ to the VP. (c) A hexagonal pyramid base 25 mm and axis 50 mm long has one of its triangular faces in the VP and edge of the base contained by that face makes angle of 30˚ with the HP. Draw its projections.
