Define the Centroid of a triangle.

Back

The Centroid is the point where the three medians of a triangle intersect, and it is also the center of mass of the triangle.

What is the relationship between the Centroid and the vertices of a triangle?

Back

The Centroid divides each median into two segments, with the segment connecting the vertex to the Centroid being twice as long as the segment connecting the Centroid to the midpoint of the opposite side.

How can you find the Circumcenter of a triangle using its vertices?

Back

To find the Circumcenter, construct the perpendicular bisectors of at least two sides of the triangle; their intersection point is the Circumcenter.
