Aray is a defined term because it

has no width or depth

is described using an undefined term

has an informal definition

travels forever in one direction

A ray is a defined term because it  is described using an undefined term .

Step-by-step explanation:

In geometry , a ray is a line with begin from one single endpoint that is known as point of origin and that extends in one direction infinitely .

The three undefined terms in geometry :

1) point   2) line  3) plane

These undefined terms in geometry are use to define the other terms in geometry.

In the definition of ray we always use two undefined terms : a) line b) point

Thus, A ray is a defined term because it  is described using an undefined term.

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
