Answer:
We know that the circumcenter of a right triangle is at the center of the hypotenuse.
Thus, the circumcenter of a triangle is: C(-1, 1/2)
Please check the attached figure.
Step-by-step explanation:
Given the triangle with the coordinates of the vertices
First plot the points on the graph, as shown in the attached diagram.
It is clear from the attached diagram that it forms a right triangle.
From the attached diagram, it is clear that the center of the hypotenuse lies on C(-1, 1/2).
Thus, the circumcenter of a triangle is: C(-1, 1/2)
Please check the attached figure.
