Question

1. a line extends: mark only one oval. infinitely in one direction infinitely in two directions infinitely in all directions in one dimension only 5. the part of a line with two endpoints is called a: mark only one oval. ray line segment plane 6. how many points are needed to determine a line? * mark only one oval. 1 2 3 4

Explanation:

• For question 4, by definition, a line extends infinitely in two directions.
• For question 5, a part of a line with two endpoints is called a segment. A ray has one - endpoint and extends infinitely in one direction, a line has no endpoints and extends infinitely, and a plane is a two - dimensional flat surface.
• For question 6, two points are needed to determine a line.

Answer:

1. Infinitely in two directions
2. Segment
3. 2
