Question

1. choose the best answer. a ___ is a part of a line that has one endpoint and extends in only direction forever. ray point line plane 6. choose the best answer. identify the postulate illustrated by the statement: line $overleftrightarrow{st}$ connects point $s$ and point $t$. postulate 1.2e: if two planes intersect, they intersect in exactly one line. postulate 1.2d: if two lines intersect, they intersect at exactly one point. postulate 1.2a: through any two points there is exactly one line. postulate 1.2b: through any three noncollinear points there is exactly one plane.

Explanation:

For the first question, by definition, a ray has one endpoint and extends infinitely in one direction. For the second question, the statement about a line connecting two points aligns with the postulate that through any two points there is exactly one line.

Answer:

1. A. ray
2. Postulate 1.2A: Through any two points there is exactly one line.
