  Let G = (V, E) be a planar triangulated graph (PTG) having every face
triangular. A rectilinear dual or an orthogonal floor plan (OFP) of G is
obtained by partitioning a rectangle into \mid V \mid rectilinear regions
(modules) where two modules are adjacent if and only if there is an edge
between the corresponding vertices in G. In this paper, a linear-time algorithm
is presented for constructing an OFP for a given G such that the obtained OFP
has B_{min} bends, where a bend in a concave corner in an OFP. Further, it has
been proved that at least B_{min} bends are required to construct an OFP for G,
where \rho - 2 \leq B_{min} \leq \rho + 1 and \rho is the sum of the number of
leaves of the containment tree of G and the number of K_4 (4-vertex complete
graph) in G.
