Question

Which term does not belong with the other three?

AB¯¯¯¯¯¯¯¯

plane CDE

FG←→

HI−→

Question 2
Explain your reasoning.


The one that does not belong is an undefined term.

The one that does not belong uses a different kind of symbol.

The one that does not belong contains fewer points.

The one that does not belong has a different number of dimensions.

Answer 1

The term 'plane CDE' does not belong because, unlike 'AB', 'FG→→', and 'HI→', it represents a two-dimensional figure, while the rest are one-dimensional.

Step-by-step explanation:

The term that does not belong with the others is plane CDE.

This is because AB, FG→→, and HI→ represent one-dimensional figures: a line segment, a ray, and a line, respectively. On the other hand, a plane is a two-dimensional figure.

Hence, the term plane CDE is the odd one out and it does not belong because it has a different number of dimensions from the rest.

Answer 2

The one that does not belong has a different number of dimensions.

Step-by-step explanation:

Given list consists of:

• a line segment (AB)
• a plane (CDE)
• a line (FG)
• a ray (HI)

Three of them have one dimension but the plane has two dimensions,

therefore the plane in the list does not belong with the other three.

So correct answer choice is:

• The one that does not belong has a different number of dimensions.
