The Coordinates of Triangle's Centroid
Loading the math board and drawing, please wait…
This example demonstrates how to find the centroid of a triangle by constructing its medians and calculating its coordinates. Key mathematical concepts include the centroid of a triangle, medians, and coordinate geometry. It uses commands like Polygon, Midpoint, Segment, and Intersect in GeoGebra. Suitable for middle school and above students learning geometric construction and coordinate geometry.
