Question

Determine whether the conjecture is true or false. Give a counterexample for any false conjecture. Given: points A, B, C, and D Conjecture: A, B, C, and D are coplanar.

Answer 1

Answer:

false

Step-by-step explanation:

Determine whether the conjecture is true or false. Give a counterexample for any false conjecture. Given: points A, B, C, and D Conjecture: A, B, C, and D are coplanar.

Not true because they not on the same plane

This is going to be true if A, B, C, all lie on the same plane.

A quadrilateral can not be on the same plane.

Answer 2

The conjecture is False. A,B,C are in one plane, D is above the plane, therefore the points are not coplanar.
The statement doesn't specify where the points are.
