+590 Hey guys, it's been a while since I posted.
Could you help me with 2 math questions?
How can I find the coordinates of the circumcenter of a triangle if I only have the coordinates of the points?
How can I find the radius of an isosceles triangle using the incenter while only knowing the measurements of the sides?
This might seem like insufficient information, so please tell me if I need to add some more explanation.
Thanks a lot.
