Question

complete each postulate.
if two intersect, then their intersection is a line.
any tv determine a.

Explanation:

According to the plane - line intersection postulate, when two planes intersect, their intersection is a line. And according to the plane - determination postulate, any two distinct points determine a line, but here the context is about planes. The correct postulate is that if two planes intersect, then their intersection is a line. And any two distinct points determine a line, but if we consider the second blank in the context of the first (related to planes), it's a mis - phrasing. Assuming the first blank: For the statement "If two... intersect, then their intersection is a line", the correct term is 'planes' (since two lines intersect at a point).

Answer:

First blank: planes.
