Q1. आकृति 6.17 (i) और (ii) में, DE || BC में AD ज्ञात कीजिए :

हल: (i)

Δ ABC में

DE || BC   दिया है |

अत: आधारभूतिक समानुपातिक प्रमेय से

Q2. किसी त्रिभुज PQR की भुजाओं PQ और PR पर क्रमशः बिन्दु और स्थित हैं |  निम्नलिखित में से प्रत्येक स्थिति के लिएबताइए कि क्या EF|| QR है |

(i)   PE = 3.9 cm, EQ= 3cm, PF = 3.6 और FR= 2.4 cm

(ii)     PE = 4 cm, QE = 4.5 cm, PF = 8 cm और RF = 9 cm

(iii)     PQ = 1.28 cm, PR = 2.56 cm, 0.18 cm और PF = 0.36 cm

इसलिए, EF|| QR नहीं है |

Q7. प्रमेय 6.1 का प्रयोग करते हुए सिद्ध कीजिए कि एक त्रिभुज की एक भुजा के मध्य -बिन्दु से होकर दूसरी भुजा के समांतर खींची गई रेखा तीसरी भुजा को समद्धिभाजित करती है  | (याद कीजिए की आप इसे कक्षा IX में सिद्ध कर चुके हैं|)

​Q8. प्रमेय 6.2 का प्रयोग करते हुए सिद्ध कीजिए की एक त्रिभुज की किन्ही दो भुजाओं के मध्य बिन्दुओं को मिलाने वाली रेखा तीसरी भुजा के समांतर होती है | (याद कीजिए की आप कक्षा IX में ऐसा कर चुके हैं ) |
