उत्तर
In the figure,
x = y ......(vertically opposite angles)
y= l .........(alternate angles)
x = I .......(corresponding angles)
1 = n .......(vertically opposite angles)
n = r .......(corresponding angles)
∴ x = y = l = n = r
Again m = k ......(vertically opposite angles)
k = q ........(corresponding angles)
∴ m = k = q
