Question 234187: Hi I'm currently doing home school and I have geometry. My question is how do you know if it's SSS, ASA or SAS in a proof? I've been doing good answering the problems, but I've only been guessing. I want to understand it better, I'm going to do state testing next couple of months.
Thanks.

Question 232517: I'm trying to do the proofs myself because I know they are important, but I'm just having trouble moving from one step to another. It's hard for me to figure out what comes next after each statement. Do you have any tips for me?

Question 223861: I really dont get how to do proofs and such. We just started on them in Geometry but our teacher completely lost me. The homework seems like it is written in a foreign language to me.
The problem is:
Suppose point T is the midpoint of RS and point W is the midpoint of RT. If XY = (supposed to be about equal to) RT and TS has a length of z, write the length of the segment in terms of z for RT.

Question 221424: I am having a really hard time with proofs in geometry. This problem comes from the Essentials of Geometry for College Students; Chapter 2.5, exercise 19:
Given: Line Segment (LS) AB is congruent to LS DE; LS AB is perpendicular to LS BD; and, LS DE is perpendicular to LS BD.
Prove: LS AC is congruent to LS EC
I can see that the figure is clearly 2 right angles adjacent to one another making them equal in measure; that point C is the midpoint of LS AE and LS DE as well as the vertex of both Triangles ABC and EDC. But, the trouble I'm having is putting them into a logical sequence. I know I have to prove one thing to move onto the next but putting them in the right order is difficult because there are so many ways to get the same answer. Can you help me with any tips that will make this process easier for me?
The answer to this specific question is given in the back of the book but I'm more interested in the process than the answer. I need to train my brain to think linearly which is what these types of exercises will do. The teacher I have isn't really helping much or should I say, isn't speaking in terms that are clicking with me.
I look forward to your response.
Thank you,
Cheri
