Question

plane r is shown. which points are coplanar and noncollinear?
points a and d
points c and d
points a, c, and d
points a, b, and d

Explanation:

1. Recall definitions:

• Coplanar: Points lie on the same plane.
• Collinear: Points lie on the same line.

1. Analyze each option:

• Points A and D: Collinear (on the same line), so not noncollinear.
• Points C and D: Collinear (on the same line), so not noncollinear.
• Points A, C, and D: Collinear (all on the same line), so not noncollinear.
• Points A, B, and D: All lie on Plane R (coplanar). A and D are collinear, but B is not on their line, so they are noncollinear.

Answer:

points A, B, and D
