Expert Solution
collapsible and non-collapsible

Collapsible

A Collapsible structure is one that is not a rigid unit by itself but depends on its external supports for rigidity

Non-collapsible

A non-collapsible structure is one that constitutes a rigid unit by itself when removed from its supports

a)As seen from the figure given the structure is not a rigid unit by itself but depends on its external support for rigidity, hence the structure is Collapsible
