Dear student,


given equation has intercept a and b. The angular bisector of O is y=x


the angular bisector of of other vertex has slope equal to tan(180 - (1/2)tan^-1 (b/a)) let us call this as m


and this passes through a,0 and equation is y = mx - ma


put x=y in the equation


=> incentre = x,y = -ma/1-m,-ma/1-m
