this one is very easy karthick.first of all if you know the slope of the bisector and one of the lines,find tan of the angle b/w them.if the value of mod comes out to be less than 1 then it is an acute angle bisector.otherwise it is obtuse.

cheers,plzzzz rate me.if you are still not clear,i can explain you more.

are yaar first you will have to find which one is acute and which one is obtuse.then from the equation check whether the given pt. satisfies the equation of obtuse angle bisector or acute angle bisector

now do rate me and from centre of mass also
