“It follows at once from the last proposition that the centre of gravity of any triangle is at the intersection of the lines drawn from any two angles to the middle points of the opposite sides respectively.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The centroid of a triangle lies where the medians intersect, each median joining a vertex to the midpoint of the opposite side.
In simple terms: Triangle centroid is at the intersection of its medians.
Key Takeaway
Use medians to locate the triangle’s balance point.
