2. Ex:1
A pentagonal prism of base 30mm and axis
75 mm is resting on H.P on its base such
that a base edge is perpendicular to V.P. A
section plane cuts the axis of the prism at a
distance of 18 mm from the top face and at
angle of 45º with the horizontal. Draw the
development of the truncated prism
4. Ex:2
A hexagonal pyramid of base 40mm and
axis 120 mm is resting on H.P on its base
such that a base edge is perpendicular to
V.P. A section plane cuts the axis of the
pyramid at a height of 45 mm from the base
and at angle of 15º with the horizontal. Draw
the development of the truncated pyramid
