Enter your answer in the box.

∠

Answer 1

@psirockin2 @Warriorz13 @JustSaiyan

Answer 2

Angle O

Answer 3

It is the same image, mirrored and rotated 180 degrees. O is D. They are the same degree.

Answer 4

Thanks.

Answer 5

Your welcome

Answer 6

@JustSaiyan must be synonymous with "JustAnswers". That would explain why @Allison does not want my help.

Answer 7

Or I just don't want your help. Nick only helped with this question.

Answer 8

Right. Do you understand the concept of 180 degree rotation? Can you explain how the process works in detail?

Answer 9

You got help with the question so surely you must understand the concept now @Allison

Answer 10

Would you I rather have said flipped? Or should I have said "180 Degree rotation from the very middle.

Answer 11

Or any point, really.

Answer 12

It's just like the other one you did. It's just the reflection of it but rotated 180 degrees.

Answer 13

@Allison, explain the concept of "180 degree rotation". What does it mean?

Answer 14

Saying that something is 'mirrored' or 'rotated' 180 degrees doesn't explain what 180 degree rotation means.

Answer 15

You rotate something 180 degrees e.e

Answer 16

This is funny to me.

Answer 17

Isn't everything?

Answer 18

"They are the same image, reflected off of point F, and rotated 180 degrees, meaning O is D, C is N, etc etc. And 180 rotation is turning an object from it's original position, to a position in the opposite direction, so if this were an arrow pointing up, it would be pointing down after the rotation.

Answer 19

I did give an explanation. So it isn't `JustAnswers`.

Answer 20

You gave a better explanation just now, which would have been acceptable to give the first time but without giving the answer. In other words you could have left out the phrase 'meaning O is D'. You could also have challenged @Allison by giving the explanation and then following up with a question like, "Do you understand what I am describing here? Do you think you might be able to figure out which point reflects the 180 degree rotation of D?".

Answer 21

But that is no different than pointing at the correct answer answer underlining it. What is the point of leading them to it, if we are still going to show them the answer?

Answer 22

Giving the answer first without giving an explanation or attempting to challenge the asker is the problem.

Answer 23

Because the goal is to help the asker understand how to solve these questions on their own.

Answer 24

It was just a question. Shut up already.

Answer 25

@Allison, this is a training session I'm having with @JustSaiyan

Answer 26

Alright. I will guide them to the answers.

Answer 27

Have it in another post. Or you might as well delete this without asking :)

Answer 28

So explanations first, followed by question, than further explanation and example if necessary.

Answer 29

Actually, IDEALLY, it's supposed to be a "discussion" in the form of

Asker: Question
Helper: Concept Question (Are you are of the existence of a particular concept/formula)
Asker: Yes or No
Helper: I can go over "Concept A" if you like
Asker: Okay
Helper: Explanation of concept provided. Do you understand Concept A better?
Asker: Yes or No
Helper: Provides Further explanations or examples if necessary. Then gets to the point where he or she asks the user, if they are able to finish or solve the rest of the problem on their own.

Answer 30

are is supposed to be "aware" btw. Are you AWARE of the existence of a particular concept/formula*

Answer 31

Shut up.

Answer 32

e.e

Answer 33

Yes I see that. I will save that. Thank you, @Hero.

Answer 34

@Allison only someone looking for JustAnswers would be displeased with this.

Answer 35

Right.
