6.4 Activity

Match the following segment types to the center that occurs at their intersection.

• Circumcenter

• Angle Bisectors

• Incenter

• Medians

• Centroid

• Perpendicular Bisectors

• Orthocenter

• Altitudes

The centroid is the point of concurrency of the 3 ____ of a triangle. 

• Medians
• Midsegments
• Perpendicular Bisectors
• Angle Bisectos

If Z is the centroid, what type of segments are drawn?

• angle bisectors
• perpendicular bisectors
• altitudes
• medians
