If the co - ordinates of the mid points of DeltaABC are D(1, 2) E(0, -1) and F(2, -1). Find the respective co - ordinates of DeltaABC. OR Find the length of the median through the vertex A(5, 1) drawn to the triangle ABC where other two vertices are B(1, 5) and C(-3, -1)

Answer»


Answer :`:.A(x_(1)y_(1))=A(4, -1)`
`B(x_(2)y_(2))=B(0, -1)`
`C(x_(3)y_(3))=C(0, -1)`
OR
`:.` Length of MEDIAN `= sqrt(37)`
