Question

1. choose the correct answer.

a plane is a flat surface that has no ___ and extends forever.
thickness
points
dimensions
size

1. choose the correct answer.

___ is the unlimited region in which all things exist.
space
plane
dimension
ray

Explanation:

• For question 5: A plane is a two - dimensional flat surface. It has length and width (two dimensions) but no thickness. Points are zero - dimensional, and saying a plane has no points is incorrect as a plane is made up of infinitely many points. Dimensions: a plane has two dimensions (length and width). Size is not the correct term here as a plane extends infinitely.
• For question 6: Space is the unlimited region in which all things exist. A plane is a flat, two - dimensional surface that extends infinitely. A dimension is a measure (like length, width, height). A ray is a part of a line that starts at a point and extends infinitely in one direction.

Answer:

1. thickness
2. Space
