Understanding Centroids and Medians in Triangles

The video tutorial explains the concept of medians and centroid in a triangle. It provides a proof that the centroid is located 2/3 along each median. The instructor uses a visual approach to demonstrate the triangle and its medians, and compares the areas of smaller triangles formed by the medians. The proof concludes by showing that the centroid divides each median into segments with a 2:1 ratio.

What is the point called where the three medians of a triangle intersect?

• Circumcenter

• Incenter

• Centroid

• Orthocenter
