    Smile Finding the circumcentre of a triangle.

    Can someone please help me work out the circumcentre of the following triangle?
    Looking for an answers with step by step instructions how to work it out. So I can see where I'm going wrong. The triangle is A (-4, -10), B (6, 14) and C (13, 7).
    Many thanks in advance!

    The point at which the perpendicular bisectors of \overline{AB}~\&~\overline{BC} meet is the circumcenter.

    Thanks I know this is the way to work it out, but I can't come to the right answer. So somewhere I'm going wrong and don't know where.

    I have the answer sheet here. So just need to see an example of it being worked out so I know where I'm going wrong.
    As I'm doing a distance learning course I'll need to wait till tomorrow for a reply from my tutor, but I'll just do that then.

    I'm not making any demands. Just asked if someone would be able to give me an explanation.
    Then you pointed out that I won't be able to get that on this forum, so I said I will wait for a reply from a tutor instead.
    I don't see where the demand is in that? Sorry to have bothered you.
