Question

Plane H is shown.

Plane H contains four points. Points A, C, and D form a diagonal line on the left. Point B is to the right of point C.

Which points are coplanar and noncollinear?

points A and D
points C and D
points A, C, and D
points A, B, and D

Answer 1

Points A, B, and D.

Reason: A, C, and D lie on the same line, so any set containing those three is collinear. B is off that line but in plane H, so A, B, and D are coplanar and not all on one line (noncollinear).
