Front

What is the definition of a median in a triangle?

Back

A median is a line segment joining a vertex to the midpoint of the opposite side.

Front

How do you find the centroid of a triangle?

Back

The centroid is found by averaging the x-coordinates and y-coordinates of the vertices.

Front

What is the relationship between the centroid and the medians of a triangle?

Back

The centroid divides each median into a ratio of 2:1.

Front

If a triangle has vertices at (0,0), (6,0), and (3,6), what is the centroid?

Back

Centroid = (3, 2)
