    Don't really understand how this is done, I think it's because I'm not really sure what a circumcentre is!!! Is it a point which is of equal distance from each oft the 3 angles???:confused:

    Thanks!:p

    EDIT: ITS 2006 SORRY!!!!

    The circumcentre is the point where you can draw a circle which passes through the three vertices of the triangle (the three "points" of the triangle)

    Edit: it's the centre of that circle.

    Therefore it's equal distance from each vertex yeah?

    As far as I know it's the point of intersection of the perpendicular bisectors of the sides, ie. the lines at right angles to the sides which split the sides in two.

    Checked my book, yeah, my last post was correct. Text & tests 4 page 90/91 explains all those, if that's the book you've got.
