Question

State a true conclusion.

1) If two planes intersect, their intersection is a line.


2) Plane Rand plane S intersect.


Conclusion:

Answer 1

The conclusion is "Plane R and Plane S form a line if they intersect."

Explanation:

Consider the provided statements.

1) If two planes intersect, their intersection is a line.

2) Plane Rand plane S intersect.

• If two points lie in a plane, then the line joining them lies in that plane.

• If two planes intersect, then their intersection is a line.

For better understanding refer the figure:

There are two planes R and S, which intersect at the line l.

Since the given two planes intersect, the using the above fact we can say that their intersection is a line.

Thus, the conclusion is "Plane R and Plane S form a line if they intersect."
