Let $\triangle ABC$ be a triangle.

The centroid of $\triangle ABC$ is the point $G$ where its three medians $AL$, $MB$ and $CN$ meet.


Also known as

A centroid is also referred to as a center of mean position.

Some sources refer to it as a mean point.

Approaches to this subject from the direction of physics and mechanics can be seen referring to it as a center of gravity.

However, it needs to be noted that the latter is merely a special case of a centroid.

Beware that some sources use the term center of gravity even when approaching the topic from a pure mathematical perspective, which can cause confusion.
