Centroids

Front

What is the definition of a centroid in a triangle?

Back

The centroid of a triangle is the point where the three medians intersect. It is also the center of mass of the triangle.

How is the centroid related to the sides 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.

What is the formula to find the centroid of a triangle given its vertices (x1, y1), (x2, y2), (x3, y3)?

Back

Centroid (G) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3).

How do you find the length of a median in a triangle?

Back

The length of a median can be found using the formula: Median = √(2a² + 2b² - c²) / 4, where a, b, and c are the lengths of the sides of the triangle.
