Yes, this is a valid argument. This argument uses the Law of Detachment.
<h3>
What is the Law of Detachment in logic?</h3>
The Law of Detachment states that if the hypothesis of a true conditional statement is true, then the conclusion must be true as well. The Law of Detachment is the most often employed deductive reasoning theory.
Given:
Points X and Y both lie on plane R.
Conclusion: Points X and Y are coplanar.
The argument is true because,
The term "coplanar" refers to "being on the same plane." Coplanar points are points that are on the same plane. A group of points in space is said to be coplanar if there is a geometric plane that contains all of them.
Hence, the Conclusion is Points X and Y are coplanar.
