Question

Postulate: If two lines intersect, then they intersect in exactly one point.
2
Theorem: If two distinct planes intersect, then they intersect in exactly one line.

Answer 1

true or false
for both

Answer 2

The first one is a postulate. Postulates are assumed to be true.
For the theorem, can you figure out how to use the postulate to prove that it is true?

Answer 3

Postulate: Through any two points, there is exactly one line.
2
Theorem: If two distinct planes intersect, then they intersect in exactly one line.
or this one

Answer 4

im confused^

Answer 5

no help plz

Answer 6

I'm not sure what you are asking.
You have the same theorem following two different postulates. What are you trying to accomplish?

Answer 7

)

Alex plots 4 points K, L, M, and N. He joins points K and L and points M and N with straight lines as shown.



Alex made the following statements about the points.

Statement 1: and intersect on the same plane.
Statement 2: and intersect at point P.

Which chart best justifies Alex’s statements?


Statement
Justification
1
Postulate: If two lines intersect, then they intersect in exactly one point.
2
Theorem: If two distinct planes intersect, then they intersect in exactly one line.

Statement
Justification
1
Postulate: If two distinct points are given, then a unique line contains them.
2
Theorem: If two lines intersect, then they intersect in exactly one point.

Statement
Justification
1
Theorem: If two lines intersect, then exactly one plane contains both lines.
2

Answer 8

this!
lol

Answer 9

Some of the information didn't copy over.
"Alex made the following statements about the points.
Statement 1: and intersect on the same plane.
Statement 2: and intersect at point P."

What and what intersect on the same plane?
What and what intersect at point P?

Answer 10

there that

Answer 11

Oh, it's just looking for a restatement of Alex's statements.
Which pair of statements means the same thing as what Alex said.

Answer 12

yeah but idk which ones :(suck at math so bad

Answer 13

This isn't even math that you need to do. The first statement is talking about lines intersecting on the same plane, and the second states that line intersect at a point.

There is one answer choice that says the exact same thing but in different words.

Answer 14

c??
