In Fig. 54, if `/_2=120^0\ a n d\ /_5=60^0,` show that `m||ndot`

In Figure,if /_2=120^(@) and /_5=60^(@), show that m||n

In Fig.55, if /_3=61^0 and /_7=118^0dot Is m||n ?

In Fig.70. if\ l m n\ a n d\ /_1=60^0, find /_2.

In Fig 66, l in e\ l m ,\ /_1=120^0\ and /_2=100^0, find out /_3\ a n d\ /_4.

In Fig.p is a transversal to lines m and /_2=120^(@) and /_5=60^(@). Prove that mn .

In Fig.104, A B C D ,\ /_O A B=150^0\ a n d\ /_O C D=120^0dot Then, /_A O C= (a) ( b ) (c) (d) (e) 80^(( f )0( g ))( h ) (i) (j) (b) ( k ) (l) (m) (n) 90^(( o )0( p ))( q ) (r) (s) (c) ( d ) (e) (f) (g) 70^(( h )0( i ))( j ) (k) (l) (d) ( m ) (n) (o) (p) 100^(( q )0( r ))( s ) (t) (u)

If A B C and DEF are two triangles such that A B C ~= F D E a n d A B=5c m , /_B=40^0 a n d /_A=80^0dot Then, which of the following is true? D F=5c m , /_F=60^0 (b) D E=5c m , /_E=60^0 D F=5 c m , /_E=60^0 (d) D E=5c m , /_D=40^0

In Fig.72, If l m ,\ n p\ a n d\ /_1=85^0, find /_2.

In Fig. 73, a transversal n cuts two lines l\ a n d\ mdotif\ /_1=70^0\ a n d\ /_7=80^0, is l m ?
