kimberlyskyy: In triangles DEF and OPQ, ∠D ≅ ∠O, ∠F ≅ ∠Q, and segment DF ≅ segment OQ. Is this information sufficient to prove triangles DEF and OPQ congruent through SAS? Explain your answer.
@Hero
@Gustavo18 is there anything about the given scenario that you don't understand or have difficulty explaining? If so, please express your confusion.
I don't get how to use SAS to prove if triangles DEF and OPQ are congruent.
Quick question. Do you know the requirements to prove two triangles congruent using SAS? If so, what are the requirements?
Two sides and the included side of a triangle are congruent to two angles and the included angle for another triangle, then the triangle are congruent
From where did you reference this information?
My school notes
Did you leave your notes at school and recalling from memory?
No I have my notes
Okay screenshot the notes for SAS and post it here. I would like to see it.
Only screenshot the postulate from your notes. I'm curious
You can either screenshot or camera phone it
can I just type it because I'm being to put the photo in the file
You've already typed it. Now I would like to see it as printed from an official textbook. Upload the entire page that way I can verify that it was indeed published in an official school-approved textbook.
its not in a textbook it is in my notebook
And where did you get the information from?
From the school textbook
And where is your school textbook?
we don't get textbooks, they at school so every student in that Classe can use it
stay
Well, sorry to say but it appears that you copied those notes incorrectly.
really?
Compare what you wrote on paper to this; \(\color{#0cbb34}{\text{Originally Posted by}}\) @Gustavo18 Two sides and the included side of a triangle are congruent to two angles and the included angle for another triangle, then the triangle are congruent \(\color{#0cbb34}{\text{End of Quote}}\)
This is what I'm referring to when I say you copied your notes incorrectly. What you wrote on paper is not what you wrote here.
oh my bad
so is the notes In the paper correct?
If you copied verbatim from your school text, the notes should be correct.
oh ok
Suppose you have two triangles \(\triangle{ABC}\) and \(\triangle{DEF}\). To prove \(\triangle{ABC} \cong \triangle{DEF}\) You need to show the following: 1. At least two corresponding sides of both triangles congruent to each other 2. The angles between the two corresponding sides for both triangles congruent to each other.
For example if you are given that \(BC \cong EF\) and \(AB \cong DE\) and \(\angle{A} \cong \angle{E}\) Then you can conclude that the triangles are congruent by Side-Angle-Side Postulate.
But for the given scenario of the problem you're tasked with, are you given two sides of one triangle congruent to two sides of the other?
No
Exactly, so what can you conclude about your given problem?
That the proof is insufficient to prove triangles DEF and OPQ congruent through SAS
Because you are not given two sides of one triangle congruent to two sides of the other
But can it be proven using another postulate? If so, which?
ASA
Correct.
But would I have to include ASA on my answer to this question?
You should because then your instructor will know that you know how to recognize the difference between a SAS scenario and an ASA scenario.
Ok thank you for your help
You're welcome.
