@Directrix

igreen · Answer

Lines, Angles, and Rays are infinite..I don't know about the Angles dimension though..

igreen · Answer

What do you think? @perl

perl · Answer

i think an angle is 2 dimensional, but i could be wrong

igreen · Answer

Same^^

Leaving you with Line and Ray..

perl · Answer

point is 0 dimensional
line is 1 dimensional
plane is 2 dimensional 
space is 3 dimensional

perl · Answer

according to this, angles are dimensionless http://mathforum.org/library/drmath/view/64034.html

ANSWERS  A, D, E, AND F ?  @perl   @iGreen  ?

igreen · Answer

What about a Ray? @perl

perl · Answer

yes, ray is 1-d and infinite

igreen · Answer

@Adam96 He just said a plane is 2 dimensional..we're looking for 1-dimensional objects..

igreen · Answer

So we take an angle out because its dimensionless?

perl · Answer

I think so

perl · Answer

angles could be defined as the interior of the space of two adjacent lines that meet at a vertex.
