a vertical cross section is where you cut the 3D figure into 2 pieces and this cut is a flat smooth cut that's completely vertical

jimthompson5910 (jim_thompson5910):

so if you have this 3D figure |dw:1360362865288:dw|

jimthompson5910 (jim_thompson5910):

and you make a cut along this dotted line |dw:1360362898802:dw|

jimthompson5910 (jim_thompson5910):

then you are cutting the figure into two pieces along a vertical cut, creating a vertical cross section

OpenStudy (kuoministers):

Yes nice explaination :)

jimthompson5910 (jim_thompson5910):

so looking at this now, do you still agree that the answer is "true" ?

OpenStudy (anonymous):

no! lol not at all thank u!! (:

jimthompson5910 (jim_thompson5910):

good, the cross section I drew formed a rectangle and this is true if you do any cross section parallel to any lateral side

jimthompson5910 (jim_thompson5910):

so it's false
