HELP PLEASE !!!
enot [183]

Given: m ∠3 = m ∠4

To Prove: ∠1, ∠2 are supplementary .

Proof : m ∠3 = m ∠4    ( Given)                                              ------------(1)

m<2 + m< 3 = 180 degrees  ( <2 and <3 form a linear pair). ----------(2)

m< 4 = m<1                            (Vertical angles are equal)       -----------(3).

Substituting, m<4 =m<1 in (1), we get

m ∠3 = m ∠1.

Now, substituting m ∠3 = m ∠1 in (2), we get

m<2 + m< 1 = 180 degrees.

Sum of m <1 and m<2 is 180 degrees.

Therefore,<em> ∠1, ∠2 are supplementary by the defination of supplementary angles.</em>
