Two medians AD and BE of triangle ABC intersect at G at right angles .

Question

If AD = 9 cm , BE = 12 cm , find length of AB?

Answer 1

Medians .

Median of a triangle joins the vertex and the midpoint of the opposite side.

It has the property that the centroid divides the median into 2:1 ratio so that the part containing vertex is twice

than the other one.

So the parameters became as shown in figure

So, from right angle triangle

So, the side of the triangle .
