i think they are true

Answer 3

Ok. Thank you! :3

Answer 4

No.

Answer 5

?

Answer 6

A plane can be named two ways.
One way is a single small-case letter.
In your case, there is no single small-case letter being used, so we'll skip that method.

Answer 7

The second way is to use three points on the plane. The points cannot be collinear, meaning, the points cannot all lie in one line.

Answer 8

So would it be A and B?

Answer 9

Through a line, there is an infinite number of planes.
If you use three points on a line to name a plane, there is an infinite number of planes you could be naming, and we don't know which specific plane you are referring to.
To name a plane using three points, you must use three points, not all on the same line, or three non-collinear points.

Answer 10

Correct. The correct choices are A and B.

Answer 11

Thanks so much for your help! :D

Answer 12

You're welcome.
BTW, choice C is incorrect because R is the name of a point on the plane. There is an infinite number of planes that contain point R.

Answer 13

You're welcome.
