Question

in the given figure, & AD 5.7 cm DB=95 cm, AE 8.7 cm and EC 14,5 cm, then prove that DC parallel BC​

Answer 1

Answer:

From figure, D and E are the points on the sides AB and AC of △ABC  

 

AD=5.7cm, DB=9.5cm, AE=4.8cm and EC=8cm 

 

DBAD=9.85.7=53 

 

and ECAE=84.8=53 

 

⇒DBAD=ECAE 

∴ BY BPT 

 

⇒DE∣∣BC 

Answer 2

Answer:

hence prove that DC || BC

Step-by-step explanation:

From figure, D and E are the points on the sides AB and AC of △ABC  

 

AD=5.7cm, DB=9.5cm, AE=4.8cm and EC=8cm 

 

DBAD=9.85.7=53 

 

and ECAE=84.8=53 

 

⇒DBAD=ECAE 

∴ BY BPT 

 

⇒DE || BC
