"2 planes contain the same point" : sometimes, it is true.
Logic: if 2 planes intersect, their intersection is a line and the line has many points. All points belongs to both planes --> 2 planes contain the same point is correct.

- Loser66

Four points lie on the same plane: sometimes, it is false --> green.

@Loser66 wait what about the one where you said a plane contains a three points is wrong, but cant they contain three at somepoint?

- AnimalLover8

They always have more than three points.

- bobobox

Oh I thought in order to have a plane you had to have three points

- Loser66

when they say "a plane contains a 3 points" they meant the plane has exactly 3 points, no more.
You are correct when saying 3 points form a plane but it doesn't mean that plain contains just those 3 points.

Yay thank you! @Loser66 I am going to reaqd through my next lesson, could you possibly help me with my next assignments after I take a crack at them? DO you have email? or instagram?

- Loser66

a line and a plane intersect at exactly 1 point: green
it is always true if the line is not on the plane
it is sometimes true if the line is on the plane. In this case, it is not "exactly 1 point" but "infinite many points"
Hence it is green

Thank you!
