Question

They form a triangle.
They are not coplanar.
They are contained in multiple planes.

Answer 1

I think it is A.

Hope my answer has helped you!

Answer 2

The true statement is:

• They are contained in multiple planes.

Explanation:

• We are given three points such that they are collinear i.e. they lie in a straight line.

Hence, such points could never form a triangle.

Because a triangle is formed with the help of three non-collinear points.

• Also, we know that the line containing the three collinear points in a plane will always lie in a plane and there may be multiple or infinite planes that may contain this line.

Hence, the points will be coplanar (i.e. they lie in the same plane)
