Side 
will be perpendicular to the bisector of the angle
. Now equations of the bisectors of lines 
and 
are
Let equation of side 
be 
and altitude through vertex 
b e
. Then equation of 
is
. If
, then
. Hence,
Hence, equation of 
is 
or 
. Similarly, if equation of 
is 
, then equation of 
will be 
. Therefore,
Hence, equation of 
is 
or 
. Finally, there are four possible equations of side 
, viz, 
or
