1.	In the figure, `/_1 =60^(@)` and `/_6 =120^(@)` Show that the lines m and n are parallel.
Answer» Given IN the figure `/_1 =60^(@)` and `/_6 =120^(@)` To show `" " m\|""\|n` Proof Since,` " " /_1 =60^(@) and /_6 =120^(@)` Here,` " "/_1 = /_3 " " `[vertically opppsite angles] `:. " "/_3 = /_1 = 60^(@)` Now ` " "/_3 + /_6 = 60^(@) +120^(@)` `rArr " "/_3 + /_6 = 180^(@)` We konw that, if the sum of two interior angles on same side of l is `180^(@)`, then lines are parallel. Hence, m`\|""\|`n
