Give the missing reasons in this proof of the Alternate Interior Angles Theorem. https://www.connexus.com/content/media/451160-12162010-102628-AM-439106449.png
if you cant view the picture (i think you cant) there is that :)
Well, for reason 3. It's definitely vertical angles are congruent but for reason 2. Can we like state a theorem? Or not? Because I wasn't allowed to do so in some proofs.
yeah, anything is fine :)
Great :) So, I think reason 2. You can say that if two lines are parallel and they are cut by a tranversal then corresponding angles are congruent.
And also we can say in reason 4. the same thing but instead of corresponding we say alternate
thanks. i give you a vote :)
You're welcome! Haha, thanks :)
