Answer 1

Answer:

here is your answer hope it..... :))

Step-by-step explanation:

here,

<a = <b ( given) ...........(1)

Also,

<b = <c ( vertically opposite angles)........(2)

=> From (1)&(2)

<a=<c

Since, corresponding angles are equal

therefore, l || m

Answer 2

Answer:

In this figure angle a=angle b

again angle b=angle c [vertically opposite angle]

so, angle a= angle c

but they are corresponding angle

so,l line parallel to m line
