Answer and Step-by-step explanation:
Solution:
Statement:
If two planes intersect their intersection is a line.
Suppose that
P =if two planes intersect.
q = then their intersection is line.
¬p = if two planes do not intersect.
¬q = then their intersection is not a line.
Converse:
If two planes intersect their intersection is a line.
P → q
Inverse:
If two planes do not intersect, then their intersection is not a line.
¬p → ¬q
Contrapositive:
If two planes intersection is not a line, then they do not intersect.
¬q → ¬p
