Answer» ABCD is a trapezium with AB || DC, E and F are points on non-parallel sides AD and\xa0BC respectively such that EF is parallel to AB show that\xa0 Given trap. ABCD in which AB || DC and EF || AB.To prove:\xa0Const: Join A-C.Proof: ∵ AB || DC and EF || AB⇒ AB || EF || DCNow, in ∆ADC, we have ...(i)[using Basic proportionality theorem]Now, in ∆ABC, we have ...(ii)Comparing (i) and (ii), we get |
