Question 237403: Prove triangle ABC is isoceles
Given: angle BAD is congruent to angle CAD
line segment AD is perpendicular to line segment BC
The answers that I originally gave were:
statement: BD is congruent to CD
reason: definition of a bisector
statement: angle BAD is congruent angle CAD
reason: ray AD is the bisector of angle BAC (given)
statement: AD is equal to AD
reason: reflexive property of equality
statement: triangle ABD is congruent to triangle ACD
reason: SAS of congruency of triangles
statement: angle ABD is congruent to angle ACD
reason: CACT
grading comments: While the effort is appreciated, the proof contains several errors. revise.

Question 237402: Okay, so im doing Properties, Definitions, Theorems & Proofs in class and i need a bit of help.
How do you write a proof for this given:
∠FOG ≅ ∠IOH
(if the symbols dont show up, the first one is an angle sign, the second is a congruent sign, & the third is another angle sign).

Question 237001: How many answers can there be for a proof? Say you put "definition of congruent angles" but the real answer is "vertical angle theorem", aren't they the same thing basically? yes, vertical angle theorem says that they share a vertex, but they are also congruent so shouldn't they both be accepted?

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?
