prove that:
It is given that:
and
are supplementary.
By definition of supplementary
⇒ .....[1]
From the figure, you can see that:
and
are also supplementary.
⇒ .....[2]
By [1] and [2] we have;
⇒
Simplify:
Since ∠2 and ∠3 are corresponding angles.
Corresponding angles states when the two lines are parallel, then Corresponding Angles are equal and vice versa.
by definition we have;
proved!
