Question

Need help ASAP!!! Using postulate and/or theorems learned in unit 1, determine whether PQR MRN. Show all your work and explain why the triangles are similar why or why are they not.

Answer 1

Answer:

ΔPQR is not similar to ΔMRN.

Step-by-step explanation:

From the triangle PQR and MRN, Applying th basic proportionality theorem, we get

$\frac{RM}{RP}=\frac{RN}{RQ}$

Substituting the given values, we get

$\frac{10}{18}=\frac{7}{21}$

$\frac{5}{9}{\neq}\frac{1}{3}$

Therefore, the basic proportionality theorem does not hold, hence the given triangles PQR and MRN are not similar that is ΔPQR is not similar to ΔMRN.
