What is the definition of a centroid in 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.

Front

If the lengths of the sides of a triangle are 6, 8, and 10, what is the circumradius?

Back

The circumradius R can be calculated using the formula R = (abc)/(4K), where K is the area of the triangle. For this triangle, R = 5.

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 centroid to the vertex being twice as long as the segment connecting the centroid to the midpoint of the opposite side.
