Explanation of Solution
Given:
The statement:
Three lines intersecting in one point are __________ coplanar.
It is not necessary that if three lines intersects in one point then they will be coplanr, they may or may not lie in the same plane.
In this figure, the three lines intersect at one point and are coplanar. And in the figure below, the three lines intersect at one point but are not coplanar.
So, it can be said that
Three lines intersecting in one point are sometimes coplanar.
