Let's take angle 3 and angle 6.

parthkohli · Answer

We know that angle 4 = angle 6 by alternate interior angle equality. And we know that 4 and 3 form a linear pair. So, we can say that angle 3 is supplementary to angle 6.

anonymous · Answer

angle 6 + angle 3 =180 ( int angle of //lines)
    angle 2 + angle 3 = 180 ( adj angle on st. lines)
    angle 2 = 180 - angle 3
                 = angle 6   ithink thats it.....................
much love lol:)

parthkohli · Answer

linear pair = two angles supplementary and adjacent.
