Question

Gina wrote the following statements.

Statement 1: If two points lie in a plane, then the line joining them lies in that plane.
Statement 2: If two lines intersect in one point, then exactly one plane contains both lines.

Which of these options is correct?

Statement 1 represents a theorem and Statement 2 represents a postulate.

Statement 1 represents a definition and Statement 2 represents a postulate.

Statement 1 represents a postulate and Statement 2 represents a theorem.

Statement 1 represents a definition and Statement 2 represents a theorem.

Answer 1

@DebbieG could you help me with this please :)

Answer 2

Well.... it's been a while since I did this stuff, lol. I think it's safe to rule out definition. Neither of them really defines anything.

Answer 3

This would probably be helpful. :)

Answer 4

alright give me one sec, ill review it

Answer 5

@DebbieG option A?

Answer 6

wait nvm

Answer 7

Statement 1 just be a postulate?

Answer 8

According to that link:

Postulate 5: If two points lie in a plane, then the line joining them lies in that plane.

Theorem 3: If two lines intersect, then exactly one plane contains both lines.

Answer 9

Like I said, this isn't an area I'm especially fluent in :) but I see no reason to think that isn't a reliable source. :)

Answer 10

So it's C! so yea

Answer 11

because statement 1 is a postulate and statement 2 is a theorem

Answer 12

Yes, I think so. :) the "exactly one plane" thing sounds more Theorem-y to me anyway. lol :)
