What is the definition of a centroid in a triangle?

Back

The centroid is the point where the three medians intersect, and it is also the center of mass of the triangle.

Front

What is the definition of an incenter in a triangle?

Back

The incenter is the point where the angle bisectors of a triangle intersect, and it is the center of the inscribed circle.

Back

The orthocenter is the point where the three altitudes of a triangle intersect.

Front

What is the definition of a circumcenter in a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect, and it is the center of the circumscribed circle.

How many points of concurrency are there in a triangle?

Back

There are four points of concurrency in a triangle: centroid, incenter, orthocenter, and circumcenter.
