Q4: A pentagonal pyramid of base side 30 mm and axis length 50 mm is resting on H.P. on one of its base corners with its axis parallel to V.P. Draw its projections when the slant edge containing the resting corner is vertical.
- Assuming axis of the pentagonal pyramid is perpendicular to H.P. and resting on H.P. (with the help of base) draw (T.V.)1 and (F.V.)1 such that one base side (say e1 a1 ) perpendicular to V.P.
- Position the (F.V.)1 such that slant edge of corner c or slant edge co perpendicular or vertical to xy (or H.P.). This is the final F.V.
- With the help of final F.V. and (T.V.)1, draw its final T.V.
