It's all good, I actually didn't think of that.

I'm sure they do have other things to do besides reading every post, but it's best to be safe lol.

Hi,

Ah I think I understand a little more now, I just needed an idea of how to actually describe it. I've come up with some answers now using the logic you mentioned, so we'll see how I do.

I believe you're talking about [name removed by admin to avoid helping them search for mentions]? That is the course I'm using, so I can see why you shouldn't give an actual answer. I just needed more of a hint on how to proceed, otherwise I do all my work myself (obviously, since I'm there to actually learn lol)

Hi! I recently discovered the forum and thought it might be helpful.

I'm having trouble with a high school geometry problem.


Imagine you have been called as a expert witness in a court case.  Your expertise is in the area of planes (not airplanes, just planes in geometry).  Your task is to convince the jury that there is, in fact, a plane based on the given information.  You must prove all three of the definitions of a plane given in Lesson 1.  You may need to include some other definitions such as the definition of an angle, a ray, etc.

Question from the lawyer:  "Dr. Expert, I only see a 70° angle here.  Kelly said that having this angle means you have a plane.  I enter Exhibit A which shows three definitions of a plane.  From what I see, none of these definitions say that an angle defines a plane.  Explain how each definition proves that an angle defines a plane."

State the definition and then explain how you can prove each definition given the angle.

14. Definition 1: a line and a point not lying on the line



15. Definition 2: three points that are not collinear



16. Definition 3: two lines which intersect in a single point or are parallel




I'm not quite understanding how to describe the answers. I see that all three definitions can create an angle, but I'm not sure how to describe this?
