5 stars! whoever gets it right

Answer 1

First, if I were a parent of a student in that class, your teacher and I would be having a serious parent-teacher meeting...

Either you know how to prove stuff in geometry, or you don't. If you do, then you should be proving stuff. If not, how can you possibly determine if a proof is correct or incorrect?

Second, you need to know the meaning of "vertical" angles, "supplementary" angles "corresponding" angles, and a couple of others. If you don't know these terms, you're in a world of hurt. Ir would also be helpful to know what the symbol, ≅ meant.

The problem is not hard. It requires you only look at your textbook and find these definitions. This is called learning.

HINT: If you know what ≅ means, you can eliminate two of them immediately.

The alternative is to wait for somebody to do it for you, you'll give them the points and you won't learn anything. Of course, they might be wrong... ;-)

Answer 2

in one component of the column, you place a "assertion," or something which you notice in the form which will help you to unravel the subject. in the column next on your assertion, you place the clarification on your assertion (commerce indoors angles, universal shape...etc.) To being a information, you're able to desire to have a "given," that's something on the subject of the form which you're informed so as which you will resolve the subject. many times, you place the given in the assertion column, and then for the clarification, you assert "given." Proofs are unfavourable;) xx

Answer 3

B because it properly identifies the relationship of the angles in a parallel line-transversal situation.

Answer 4

b is the correct proof
