A diagonal of a solid does NOT lie in any of the faces

jim_thompson5910 · Answer

You're listing diagonals of the individual rectangular faces.

anonymous · Answer

like RC as an example?

jim_thompson5910 · Answer

yes, RC is a diagonal for the rectangle BRSC...but NOT a diagonal for the solid

anonymous · Answer

so would that be considered on of the diagonals they are asking for or no?

jim_thompson5910 · Answer

no it would not be considered one of the diagonals they are looking for

anonymous · Answer

okay. so then if they dont overlap the face of the angle, then the diagonal would be RB?

jim_thompson5910 · Answer

RB is an edge, which is not a diagonal at all

jim_thompson5910 · Answer

RD however is a diagonal of the solid

anonymous · Answer

ohhh cuz they go from one side of the angel to the other?

jim_thompson5910 · Answer

one point to the opposite point, yes

jim_thompson5910 · Answer

and it's almost (not quite though) as if the diagonal passes through the center of the solid

anonymous · Answer

i thought it was from side to the other on the faces. O.o okay i get it thanks a bunch :)
