Question 176065: This proof is very hard to explain and is a weird figure!!! Please try to follow me on this. This proof is also very long. I would appreciate it so much if you take your time to read this. Im sorry to bother you, please try your best, and email if you do or do not know the answer. Thank you.

Given: Angle AKE is congruent to Angle REK
Angle 1 is congruent to Angle 4

Prove: Line SK is parallel to Line TE.

First of all, there is two lines, Line S is a straight line above Line T. They look parallel already. Next, point K is on Line S, bout in the middle of it. And point E is about almost to the end of the line on the right hand side of Line T. This is were it gets confusing. Point A is above and to the right of point K, about a 45 degree angle, if you draw an imaginary line right above point K. From point K there is a segment that goes down to connect to point E. And from point E, the line goes down to point R which is below line T, but directly in line with point K. Angle 1 is the first angle made at the top, and Angle 2 is right below it, and then Angles 3 and 4 are where K and E meet and where E drops down to meet R. 3 is above 4.

I know this a long proof, and please help me, i really need help, because if i dont get this proof right, i will fail my exam, because it is a take home proof. THANK YOU 4 YOUR TIME.

Question 184811: Hi. Thank you for helping me on this one. I don't even know where to begin with this problem. I will enter the question below:
PROVE:
if the base angles of a triangle are congruent, then the triangle is isosceles.
Part A:
draw and label a diagram that includes:
1. a triangle with each vertex and the given information labeled
2. all other information needed to present the proof
Part B:
construct a formal proof of the theoren including:
1. given statement
2. other statements that lead to a proof of the theorem
3. a reason for each step
4. a conclusion that proves the theorem
I think that if I had some guidance on knowing what information needs to be available for the given information I might be able to construct the proof and reasons. I just don't know what information is required in order to do the intended proof and I don't know where to even start. Normally, when I ask for help on here I amnot quite so lost and I provide all of my detailed work as well-but this time I am at a complete loss and do not know where to go from here. If someone could help me and give me some well explained guidance I may be able to do this problem. But I do need help! Thank you so much and I am sorry that I don't have any real work done to show you as well-but as I said I am lost!
Thanks again.

Question 185839: My daughter and her 3 friends are all in the 11th grade Geometry class, and were doing ok until it came to proofs. They do not understand how to do them at all, and their teacher is pregnant and not happy, she wants to keep on moving along, while they are stuck. Now they have to be able to do these to move on, and the class is moving on after Friday. These 3 are A/B students generally, but all have C's or worse. Can someone explain to them, in simple terms, how to do proofs? Any help will be greatly appreciated.
