Best ResponseYou've already chosen the best response.3OK, so, what are some ways to prove two traingles are congruent? You want one of them as a goal.

e.mccormick

Best ResponseYou've already chosen the best response.3There are 5 ways. sss, sas, asa, aas, and hl. The last only applies in right triangles: http://www.regentsprep.org/regents/math/geometry/gp4/ltriangles.htm You need to move toward one of those. So you need to take what is given and show how it applies to parts of those, then use other rules to fill in mising bits. For example, it says D is the midpoint of AC. By the definiton of a midpoint that means AD = DC. So that means antyhing wih a side might use that.

Best ResponseYou've already chosen the best response.0okat its starting to make sense but how to do i put that into proof , statements and reasons?

Best ResponseYou've already chosen the best response.3"By definition, a midpoint of a line segment is the point on that line segment that divides the segment two congruent segments." from http://www.regentsprep.org/regents/math/geometry/gcg2/lmidpoint.htm As I said you use the definition of midpoint to prove that one. What other sides can you prove would have the same measure?

Best ResponseYou've already chosen the best response.0um so i use the definition as my proof? cbd would have the same measurements

e.mccormick

Best ResponseYou've already chosen the best response.3You use the "definition of midpoint" for the reason for that one part, ad = dc cbd? Do you mean the angle? I asked about sides at this point.

Best ResponseYou've already chosen the best response.0im confused on how to do this paper i dont get what your explaining i cant figure it out so i can write it down

e.mccormick

Best ResponseYou've already chosen the best response.3Well, like I said, you have only 5 ways you can prove two triangles are congruent. So you must prove each part of one of those 5, then you can prove that 5.

Best ResponseYou've already chosen the best response.0okay i get that so for proof for the 1st one i put AD = DC

e.mccormick

Best ResponseYou've already chosen the best response.3Well, usually you start by listing the given you would use first. So you need "D us midpoint of AC" and "Given" Then for the 2nd one you can use AD = DC, definition of midpoint.

Best ResponseYou've already chosen the best response.0proof is D is midpoint of Ac wait im so lost uggghhhhhhh how am i ever gonna finish this stupid paper

Best ResponseYou've already chosen the best response.3It is just a couple more. See, there are three sides, right? And SSS is a proof of congruance. In two lines you just proved one side. So, how would you prove a second side?

e.mccormick

Best ResponseYou've already chosen the best response.3Well, what ese is given?

e.mccormick

Best ResponseYou've already chosen the best response.3There are two givens and a diagram: ABC is isosceles D is the midpoint of AC. We already used "D is the midpoint of AC." so what can you get from "ABC is isosceles"

Best ResponseYou've already chosen the best response.0or A is the midpoint to BC

e.mccormick

Best ResponseYou've already chosen the best response.3No. Not BC = AC. Which sides on the diagram have the same mark?

e.mccormick
 one year ago
Best ResponseYou've already chosen the best response.3Yes. So the 3rd line is ABC is isosceles, given BC = BA, definition of isosceles

e.mccormick

Best ResponseYou've already chosen the best response.3Well, 3rd and 4th lines.

e.mccormick
 one year ago
Best ResponseYou've already chosen the best response.3OK, so that covers 2 of the sides. One more side and you prove SSS works. So what is the last side you need?

e.mccormick
 one year ago
Best ResponseYou've already chosen the best response.3Yes. And DB is a shared side! So it is the same thing. There is a tecnical name for this: Reflexive Property of Equality http://www.mathwords.com/r/reflexive_property.htm The reflective property basically says that everything is itself. It is sstupid, but math actually has a rule to prove this! So the 5th line is: DB = DB, Reflexive Property of Equality

e.mccormick

Best ResponseYou've already chosen the best response.3One last line. The SSS line. ADB = CDB, SSS

e.mccormick

Best ResponseYou've already chosen the best response.3And that is it. See, you prove each side, in this case, then say because the sides are = the triangles are =. So you prove each part then the whole. I'll give a plain language example.

Best ResponseYou've already chosen the best response.0can you write all the lines out in order so first the proof then statements then reasons cause i cant figure out how to write that part

Best ResponseYou've already chosen the best response.3I want to prove I have done my chores. I have a list of do dishes, make bed, and feed cat. I show that my bed is made. I show that the dishes are on the shelves so they mist have been done. I show that the cat bowl is empty... oops. Proves nothing! But I show the cat is happy and not hungry. So I must of fed the cat. All three things are done so the list must have been done. Proof I did my chores. That is what a proof is about. Showing how things have been done and are linked together. The lines for your proof are here, it this post. Just need to copy them in order.

Best ResponseYou've already chosen the best response.3That is really what proofs are like. Just how you would prove to a parent that you did what you were told to do.

Best ResponseYou've already chosen the best response.0but what parts do i use to make that proof your not telling me your using english for math and its confusing me .

Best ResponseYou've already chosen the best response.3Well, from the top down in this post, when did I say things would be line(s) in your proof of triangles?

Best ResponseYou've already chosen the best response.0maybe but everything you explained is mixed up in different text and im confused and i asked you if you could straighten them out basically because im lost i wouldnt be asking otherwise.

Best ResponseYou've already chosen the best response.0okay .. can you help me make sure i got these right then?

anonymous

Best ResponseYou've already chosen the best response.0so the 1st one is AD = DC as the proof right?

e.mccormick

Best ResponseYou've already chosen the best response.31) D is Midpoint of AC, Given 2) AD = DC, definition of midpoint

Best ResponseYou've already chosen the best response.0Do you understand how i have to write this paper out as? Proof is one then, statements then, reasons

e.mccormick

Best ResponseYou've already chosen the best response.3Yes. That is why I put a comma.

e.mccormick

Best ResponseYou've already chosen the best response.3#) statement , reason

Best ResponseYou've already chosen the best response.0that doesnt make sense there so 3 commas not 2? i need proof as well as statement and reason

e.mccormick

Best ResponseYou've already chosen the best response.3\( \begin{array}{lcl} Statements & \qquad & Reasons \\ \hline \text{D is the midpoint of AC} & \qquad & \text{Given} \\ AD = DC & \qquad & \text{Definition of midpoint} \\ \end{array} \)

e.mccormick

Best ResponseYou've already chosen the best response.3Yes. And I am trying to show how it would look when filled out.

Best ResponseYou've already chosen the best response.0is my proof ABD = CBD

Best ResponseYou've already chosen the best response.0i know but wheres the proof???

e.mccormick

Best ResponseYou've already chosen the best response.3Which is the LAST line. You build up to that.

e.mccormick

Best ResponseYou've already chosen the best response.3Those are the first two lines. There are six lines.

Best ResponseYou've already chosen the best response.0okay can you write out a the lines? ive been trying to write them down and put it together but i cant get em right :/

Best ResponseYou've already chosen the best response.3Those are the only two that were not written out clearly. The first two. The 3rd, 4th, 5th, and 6th are all in that image: http://assets.openstudy.com/updates/attachments/55ef8588e4b0dedaa9edb1a4e.mccormick1441830203955proof.png I did them as: Statment, reason ABC is isosceles, given They are all there.

Best ResponseYou've already chosen the best response.3As I said, it is right there, six lines. All six are typed out.
