unit 1 quiz 1
geometry a / unit 1 - the basics of geometry

1. choose the best answer.

identify the postulate illustrated by the statement. line ( overleftrightarrow{st} ) connects point ( s ) and point ( t ).
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.
postulate 1.2e: if two planes intersect, they intersect in exactly one line.

1. choose the best answer.

an endpoint is at both ends of a line ____ or at the start of a ray.
type
location
segment
space

Explanation:

For the first question, the statement about a line connecting two points aligns with the geometric postulate that through any two points there is exactly one line. For the second question, by the definition of a line segment (it has two endpoints) and a ray (it has one endpoint at its start), the correct term is "segment".

Answer:

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