Looked, and that sounds about right (algebra II would translate to about grade 11 I think ). I should specify that in the examples I posted, we had to find the coordinates of the incenter (the point at which the angle bisectors meet ), and the equation of the inscribed circle. I had posted incorrect information.
The equation of the angle bisector can was derived with the help of the distance formula (distance from a point to a line ) described in the above post.
PS: I wish the edit button did not disapear!
Thanks
