Type 9-1 A Section of the Body of Rotation
Find all the shapes that cannot be cross-sections of the body of
rotation when a cone intersects with a plane.
1 Draw the cross-sections when a cone intersects with a plane that is
perpendicular to the axis of rotation, and when a cone intersects with a
plane that includes the rotation axis
2 Draw the cross-sections when a cone intersects with a plane that passes
through the base, and when a cone intersects with a plane that does not
pass through the base.
3 Find all the shapes that cannot be cross-sections when a cone intersects
with a plane.
