Explanation:

Identify geometric terms for the first three statements

1. A flat surface containing infinitely many intersecting lines extending forever in all directions is a plane.
2. A portion of a line with two endpoints is a line segment (or simply segment).
3. A statement assumed to be true based on basic geometric principles is a postulate (or axiom).

Identify the set operation for the fourth statement

1. The statement describes elements belonging to the first set and the second set.
2. The symbol used is \(\cap\), which represents the intersection of two sets.

Answer:

Question 1

<blank>A plane</blank> is a flat surface that contains infinitely many intersecting lines that extend forever in all directions.

Question 2

<blank>A line segment</blank> is a portion of a line with two endpoints.

Question 3

<blank>A postulate</blank> is a statement that is assumed to be true based on basic geometric principles.

Question 4

The <blank>intersection</blank> of two sets if it is in the first set and it is in the second set. The symbol used is \(\cap\). The key word is "and".
