 \bf \Huge \implies \: Given :

 \bf \large \longrightarrow \angle1 = 60 \degree

 \bf \large \rightarrow \angle  \: 2 =  \frac{2}{3}  \:  \: of  \: \: a \:  \: right \:  \: angle

 \bf \large \leadsto \:  =  \frac{2}{3}  \times 90 \degree \:  = 60 \degree \\

 \bf \Huge \implies \: To  \:  \: Prove:

Prove that m || n.

 \bf \Huge \implies \: Solution :

 \bf \small \leadsto \angle \: 3 =  \angle \: 2 \:  (vertically  \:  \: opposite  \:  \: angles) 

 \bf \large \iff \angle \: 3 = \:  60 \degree

 \bf \small \iff \: Since, ∠1=∠3 \: corresponding  \:  \: angles

So, corresponding angles are equal .

 \:

Then m n.

 \:  \:

Hence , Proved
