Question

intersecting lines are coplanar. options: never, sometimes, always

Explanation:

Step1: Recall the definition of coplanar lines

Coplanar lines are lines that lie on the same plane.

Step2: Analyze intersecting lines

If two lines intersect, they share a common point. By the postulate of plane geometry, any two intersecting lines determine a unique plane. That is, there is exactly one plane that contains both of the intersecting lines. So, intersecting lines must lie on the same plane, meaning they are always coplanar.

Answer:

always
