Front

What is the Incenter of a triangle?

Back

The point where the three angle bisectors of a triangle intersect.

Front

What is the Centroid of a triangle?

Back

The point where the three medians of a triangle intersect.

Front

What is the Orthocenter of a triangle?

Front

In a triangle, how many points of concurrency are there?

Back

There are four: Circumcenter, Incenter, Centroid, and Orthocenter.

Front

What is the relationship between the centroid and the lengths of the medians?

Back

The centroid divides each median into a ratio of 2:1.
