Question

the intersection of plane $\mathcal{a}$ and plane $s$ will be
the intersection of lines $n$ and $k$ is
point $x$ is the intersection of

Explanation:

Step1: Intersection of two planes

When two planes intersect, their intersection is a line. In the given figure, plane \( A \) and plane \( S \) intersect along line \( f \).

Step2: Intersection of two lines

When two lines intersect, their intersection is a point. Line \( n \) and line \( k \) intersect at point \( V \).

Step3: Intersection of a line and a plane

Point \( X \) lies on line \( m \) and also lies on plane \( A \). So, point \( X \) is the intersection of line \( m \) and plane \( A \).

Answer:

1. Line \( f \)
2. Point \( V \)
3. Line \( m \) and plane \( A \)
