I not at all sure that I understand what it is you require.
Is this it? Say that
are the three vertices of the triangle and point
.
Now you want a line in the plane of the triangle through
which is perpendicular to
.
If that is the case, the solution a straightforward.
Otherwise, you need to try again to explain the question.
