Question

in ∆PQR, MN || QR and PM/MQ=2/3. (I) find MN/QR. (ii) Prove that ∆OMN and ∆ORQ are similar. (iii) Find area of ∆OMN: area of ∆ORQ.​

Answer 1

Answer:

(I) ans is 2/5

(ii) In triangle orq and omn

I) o is common angle

ii) orq angle = omn angle (c.angle)

therefore orq similar to omn (angle-angle similarity)

iii) 1:4
