Question

plane x 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:

Step1: Understand coplanar and non - collinear

Coplanar points lie on the same plane. Non - collinear points do not lie on the same straight line.

Step2: Analyze each option

• For points A and D: Only 2 points. Collinear (as 2 points always form a line).
• For points C and D: Only 2 points. Collinear.
• For points A, C, and D: Collinear (from the figure, C lies on the line through A and D).
• For points A, B, and D: Lie on plane \( X\) (coplanar) and not on the same straight line (non - collinear).

Answer:

points A, B, and D
