# 7 Best Free Online Centroid Calculator Websites

Here is a list of **best free online centroid calculator websites**. The centroid is the geometric center of an object. It is also known as a point where all the lines originated from the vertices of a shape meet. Knowing the Centroid of a two-dimensional shape is quite significant as it enables users to calculate area and moment of inertia values. Similarly, the Centroid helps calculate the the center of balance and various mechanics problems for 3D objects.

## Frequently Asked Questions

The centroid of a triangle is the point where the three medians of the triangle intersect. A median is a line segment that connects a vertex of a triangle to the midpoint of the opposite side. The centroid is often denoted by the letter G.

The centroid is the geometric center of an object. It is also known as a point where all the lines originated from the vertices of a shape meet.

No, the orthocenter and centroid are not the same in geometry. They are distinct points associated with a triangle.

The rule of the centroid in a triangle involves the relationship between the centroid and the medians of the triangle. The centroid is the point where the three medians intersect, and an interesting property is that the centroid divides each median into two segments in a specific ratio. The segment closer to the midpoint of the opposite side is twice as long as the segment closer to the vertex.
