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.

Gustavo18:

@Hero

Hero:

@Gustavo18 is there anything about the given scenario that you don't understand or have difficulty explaining? If so, please express your confusion.

Gustavo18:

I don't get how to use SAS to prove if triangles DEF and OPQ are congruent.

Hero:

Quick question. Do you know the requirements to prove two triangles congruent using SAS? If so, what are the requirements?

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

Hero:

From where did you reference this information?

Gustavo18:

My school notes

Hero:

Did you leave your notes at school and recalling from memory?

Gustavo18:

No I have my notes

Hero:

Okay screenshot the notes for SAS and post it here. I would like to see it.

Hero:

Only screenshot the postulate from your notes. I'm curious

Hero:

You can either screenshot or camera phone it

Gustavo18:

can I just type it because I'm being to put the photo in the file

Hero:

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.

Gustavo18:

its not in a textbook it is in my notebook

Hero:

And where did you get the information from?

Gustavo18:

From the school textbook

Hero:

And where is your school textbook?

Gustavo18:

we don't get textbooks, they at school so every student in that Classe can use it

Gustavo18:

stay

Hero:

Well, sorry to say but it appears that you copied those notes incorrectly.

Gustavo18:

really?

Gustavo18:

Hero:

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 \(\color{#0cbb34}{\text{End of Quote}}\)

Hero:

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.

Gustavo18:

oh my bad

Gustavo18:

so is the notes In the paper correct?

Hero:

If you copied verbatim from your school text, the notes should be correct.

Gustavo18:

oh ok

Hero:

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.

Hero:

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.

Hero:

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?

Gustavo18:

No

Hero:

Exactly, so what can you conclude about your given problem?

Gustavo18:

That the proof is insufficient to prove triangles DEF and OPQ congruent through SAS

Gustavo18:

Because you are not given two sides of one triangle congruent to two sides of the other

Hero:

But can it be proven using another postulate? If so, which?

Gustavo18:

ASA

Hero:

Correct.

Gustavo18:

But would I have to include ASA on my answer to this question?

Hero:

You should because then your instructor will know that you know how to recognize the difference between a SAS scenario and an ASA scenario.

Gustavo18:

Ok thank you for your help

Hero:

You're welcome.
