Homework Help Overview

The discussion revolves around triangle congruence in geometry, specifically addressing whether the segments AB and BC can be concluded as equal based on given information and justifications. Participants are analyzing the conditions under which triangle congruence can be established, referencing specific properties such as right triangles and angle bisection.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are exploring different justifications for triangle congruence, questioning the validity of certain assumptions, and discussing the implications of specific triangle properties. There is a focus on the relevance of angle bisectors and the conditions under which they can be claimed.

Discussion Status

The discussion is active, with participants providing various perspectives on the problem. Some guidance has been offered regarding the use of triangle congruence criteria, and there is an ongoing exploration of the assumptions made in the original poster's reasoning.

Contextual Notes

Participants note constraints related to the clarity of the provided information, as well as the use of terminology that may be restricted in the forum context. There is also mention of specific geometry rules that may affect the conclusions drawn.

Geometry Triangle Congruence - **Edited to include diagram**

Homework Statement



Hi! The three simple geometry problems are in the attached photo. Sorry if they're difficult to read. I haven't seen this information in so long, and could use some help. :D

Can you use the given information to determine that (AB) = (BC) ̅? Justify your answer.


The Attempt at a Solution




1. I would say that we cannot conclude AB = BC, because we have ***, which you can't conclude anything from.

2. Yes, AB = BC, because we have two right triangles, BE = BE, and AE = EC. Thus the hypotenuses must be the same?

3. I feel like the answer is yes here. Can one say that BD bisects angle ABC? Therefore, we have ASA?

Thanks a lot guys/girls!

You are correct. Answers are: no, yes, yes.

For #1 you haven't given a reason.

For # 3, how do you know the the angle is bisected? BTW: You could have used SAS immediately.
 
Thanks Sammy!

For #1, I apparently typed a banned word via the abbreviation for angle-side-side. Whoops!

Is that a legitimate reason now to say no?

Also, for #3, I see now that the angle bisection comment is irrelevant and not necessarily justified either. When can you say that an angle is bisected?

Thanks again!

Yes, for #1 A$$ is as good as SSA .
