Question

Lines m and n are parallel and t is not perpendicular to m. Which is NOT a pair of corresponding angles?

<1 and <5

<4 and <5

<4 and <7

<3 and <8

Answer 1

<4 and <5

Answer 2

Well, you can see that \(\color{blue}{ ∠2 }\), \(\color{blue}{ ∠3 }\), \(\color{blue}{ ∠6 }\), \(\color{blue}{ ∠8 }\) are EQUAL.

and \(\color{blue}{ ∠1 }\), \(\color{blue}{ ∠4 }\), \(\color{blue}{ ∠5 }\), \(\color{blue}{ ∠7 }\) are EQUAL.


So in all options they are equal, but which of them don't correspond?

@CO_oLBoY thanks for blurring out the answer.
