Points of Concurrency in Triangles

Mr. Zazic presents a video tutorial on points of concurrency in triangles, covering perpendicular bisectors, medians, altitudes, and angle bisectors. Each type of line intersects at a specific point: circumcenter, centroid, orthocenter, and incenter, respectively. The video includes a mnemonic song to help students remember these concepts.

What is the point called where the perpendicular bisectors of a triangle meet?

• Orthocenter

• Centroid

• Circumcenter

• Incenter

Which point of concurrency is equidistant from the vertices of a triangle?

• Centroid

What is the point called where the medians of a triangle meet?

• Circumcenter

• Centroid

The centroid divides each median into two segments. What is the ratio of these segments?
