Question

1/2× pm×(PQ+MN)
pm =? , PQ=4.5, MN= 12
solve it correctly please​

Answer 1

Answer:

Converse of basic proportionality theorem :

If a line divides any two sides of a triangle in the same ratio then the line must be parallel to the third side.

Step-by-step explanation:

(i) Given : PM = 4 cm, QM = 4.5 cm , PN = 4 cm, and NR = 4.5 cm.

    In ∆PQR,

    PM/QM = 4/4.5

    And,  PN/NR = 4/4.5

    so, PM/QM  = PN/NR

    Hence, MN  || to QR

    [By Converse of basic proportionality theorem]
