a,b,and c are coplanar.
true or false?

Answer:
I think the answer might be false.
Step-by-step explanation:
Points or lines are coplanar if they lie in the same plane. Example 1: The points P , Q , and R lie in the same plane A . They are coplanar .
A plane is two-dimensional doubly ruled surface spanned by two linearly independent vectors. The generalization of the plane to higher dimensions is called a hyperplane. The angle between two intersecting planes is known as the dihedral angle.
