Given ∠9≅∠13.which lines, if any, must be parallel based on the given information? justify your conclusion. c∥d, converse of the same-side interior angles theorema∥b, converse of the alternate interior angles theoremc∥d, converse of the corresponding angles theoremnot enough information to make a conclusion

<9 and <13 are corresponding angles according to the corresponding angles postulate. The converse of the corresponding angles postulate is simply the reverse of the corresponding angles postulate.

So, the answer would be c||d, converse of the corresponding angles theorem.

Just FYI, it's the corresponding angles postulate.

Happy Solving!

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.
