Plane H is shown. Which points are coplanar and noncollinear? points A and D points B and C points A, C, and D points A, B, and D

OpenStudy (samirahdanyel):

jhonyy9 (jhonyy9):

first of all do you know what mean coplanar and collinear ?

OpenStudy (samirahdanyel):

yes

jhonyy9 (jhonyy9):

so than you can answering this question easy

jhonyy9 (jhonyy9):

what mean coplanar ?

OpenStudy (samirahdanyel):

they're in the same plane

jhonyy9 (jhonyy9):

exactly - so how you see these points all are or not are in the same plane ?

OpenStudy (samirahdanyel):

i think its the last answer

jhonyy9 (jhonyy9):

from this last choice A and D are collinear - so not is right

OpenStudy (samirahdanyel):

so its gotta be choice b because b isnt on the line

jhonyy9 (jhonyy9):

yes with choice B. you are right sure - but do you understand it now sure ?

OpenStudy (samirahdanyel):

yeah i do

OpenStudy (samirahdanyel):

thank you

jhonyy9 (jhonyy9):

ok was my pleasure good luck bye bye

OpenStudy (agent0smith):

@jhonyy9 choice D is correct The question asks "NONcollinear" A, B and D are not collinear

OpenStudy (agent0smith):

@samirahdanyel

OpenStudy (agent0smith):

points B and C are collinear - you could draw a line between them. You cannot draw a line through A, B, D.
