Question

" If two vertices of a triangle are "(8,4),(9,-2)" and the centroid is "(0,0)" then "],[" find the third vertex."]

Answer 1

Answer:

(-17,-2)

Step-by-step explanation:

By given two points we can find the mid point of both the vertices.Centroid is the point where all the three lines meet and these lines bisects the opposite side.Hence the the line coming from the unknown vertex will pass through the centroid and meet at the mid point of the given two vertices. So we can find the mid point.Now we know that centroid divides the line in 2:1 ratio.So by applying the intersection formula we can find the other unknown vertex.
