Step-by-step explanation:

Draw a line 'l' parallel to AB and CD through F.

From the figure

+ =180° ---(1)

/* Sum of interior angles same side of the transversal are supplementary */

= ---(2)

/* alternate angles */

Therefore,

+ =

=> = -

=> = - --(3) \* From (2) *\

Now, put (3) in equation (1), we get

+ - = 180°
