To extend Dave's method, once again more difficult to describe than
do. Take the two pieces of wood you want to use and lay one piece on
one of the walls as you would want it to be, with one corner over the
outside of the angle of the 'L'. Lay the other piece over it,
supporting it so that it is horizontal so that the outer corner is
exactly over the outer corner of the first piece. At the inner part
of the corner mark both pieces of wood. Cut both pieces from the
mark to the corner and you have bisected the angle.

Thats better than my method, thanks. Bit more time to set up, but much more
accurate.
