### Lesson Focus

#### The Definition of Space

Geometry

You will discover and learn about the fundamental ideas you need to understand in order to make sound geometric conjectures and prove them.

### Now You Know

After completing this tutorial, you will be able to complete the following:

• Define three-dimensional Euclidean space.

### Everything You'll Have Covered

What is three-dimensional Euclidean space?

~ The space that has infinite width, length, and height is called three-dimensional Euclidean space.

How does three-dimensional Euclidean space differ from two-dimensional Euclidean space (from planar geometry)?

~ In two-dimensional Euclidean space (i.e., in a plane) all objects may have length and width, but have no thickness. In three-dimensional Euclidean space, objects may have length, width, and thickness.

Can all physical objects be modeled by objects in three-dimensional Euclidean space? Why or why not?

~ Answers will vary. Certainly, any object with length, height, and width can be modeled by an object in three-dimensional Euclidean space. The physical objects we experience all have finite length, width, and height and thus can all be modeled by objects in three-dimensional Euclidean space.
