Question

I don't want the first one answer I want the second and third one please answer I have searched for this question answer many times but not got please and also tell which type of angle it is only you can tell is corresponding or alternate angle please tell​

Answer 1

$\huge \fbox {A} \fbox{n}\fbox{s}\fbox{w}\fbox{e}\fbox{r}$

(b) Consider to the attachment

In line m ,

x + 145° = 180°(linear pair)

x = 180 - 145 = 35°

⇒ Angle on l and angle on m are equal (35°)

$Therefore, by \: alternative \: interior angles \: property$

$l || m$

Alternative method, you can find the angle opposite to the angle on line l

(c) Consider to the attachment

In line m ,

60° + y = 180°(linear pair)

y = 180 - 60 = 120°

⇒ Angle on l and angle on m are not equal(125° ≠ 120°).

$Therefore, l \: is \: not \: parallel \: to \: m.$

Alternative method, you can find the angle opposite to the angle on line l
