What is the main characteristic of a three-dimensional space?

• It has four axes at 90 degrees to each other.

• It has one axis.

• It has three axes at 90 degrees to each other.

• It has two axes at 90 degrees to each other.

How can a 3D vector be visualized on a computer screen?

• By using 3D glasses.

• By rotating the screen to see different angles.

• By imagining the vector pointing out of or into the screen.

• By using colors to represent depth.

What symbol is used to represent a vector coming out of the page?

• A dot.

• A square.

• An arrow pointing upwards.

• A circle.

What does an 'x' symbolize in 3D vector notation?

• A vector pointing upwards.

• A vector going into the page.

• A vector pointing to the right.

• A vector coming out of the page.

Why don't we represent the size of vectors with 3D vector symbols?

• Because size is only represented with 2D vectors.

• Because it is too complex to calculate.

• Because size is not important in 3D vectors.

• Because 3D vectors are always the same size.
