Whats the question?

anonymous · Answer

How do you solve this? I'm completely lost

ranga · Answer

The circumcenter is where the perpendicular bisectors of the sides of the triangle intersect.

anonymous · Answer

Yes, but how do you solve it....

ranga · Answer

From the bottom side of the triangle that is parallel to the x axis, you can find the x-coordinate of the circumcenter.  Find the midpoint of the x-coordinates of: (-4,-4) and (-1, -4).

ranga · Answer

You can find the y-coordinate of the circumcenter from the midpoint of the y-coordinates of: (-4,-4) and (-4, 0).  

Midpoints of (x1, y1) and (x2, y2) is: ((x1+x2)/2, (y1+y2)/2)

anonymous · Answer

(-4+(-4))/2 (-4+0)/2 ?

ranga · Answer

(-4, -4) and (-1, -4).  The line joining these two points is parallel to the x axis as seen in the bottom side of the triangle.  The perpendicular bisector divided the line into 2 equal parts.  We can find the x coordinate of the mid point: (x1 + x2)/2 = (-4 + -1)/2 = -5/2

anonymous · Answer

Oh, that makes a little more sense, thank you

ranga · Answer

The perpendicular bisector of the left side of the triangle will pass through the midpoint of (-4, -4) and (-4, 0).  We can find the y coordinate as follows: (y1 + y2)/2 =
(-4 + 0)/2 = -2
These two bisectors will intersect at (-5/2, -2).
