4.6 Medians of a Triangle
Activity 4.6 Intersecting Medians
Vocabulary A MEDIAN of a triangle is a segment from a vertex to the midpoint of the opposite side. A CENTRIOD is the point where the three medians of a triangle meet.
Example 1 Draw a median
Intersection of Medians of a Triangle Theorem The medians of a triangle intersect at the centroid, a point that is two thirds of the distance from each vertex to the midpoint of the opposite side.
Example 2 Use the centroid of a triangle
Example 3 Use the centroid of a triangle
