self - assessment 1 i do not understand. 2 i can do it with help. 3 i can do it on my own. 4 i can teach someone else.

1. in the diagram in example 2, which postulate allows you to say that the intersection of plane p and plane q is a line?
2. use the diagram in example 2 to write an example of each postulate.

a. two point postulate
b. line - point postulate
c. line intersection postulate

Explanation:

Step1: Identify relevant postulate

The Plane - Plane Intersection Postulate states that if two planes intersect, then their intersection is a line.

Step2: Examples for postulates

a. Two Point Postulate: Given two points in the diagram, there is exactly one line through them.
b. Line - Point Postulate: A point on a line in the diagram shows a line contains at least two points.
c. Line Intersection Postulate: If two lines in the diagram intersect, then they intersect in exactly one point.

Answer:

1. Plane - Plane Intersection Postulate
2. a. Given two points, one line through them.

b. Point on line shows line has points.
c. Intersecting lines intersect at one point.
