Question

Are points D, E, and F collinear?

Answer 1

hint : collinear = \(co ~~linear\)

Answer 2

which means, they should be on some SAME line

Answer 3

Look at the picture,
Is there some line that passes through all of these 3 points ?

Answer 4

There is. Since the diagram is three dimensional, I was wondering if there's a special rule that changes things.

Answer 5

good :)
definition wont change. if a line cuts thru the points, they're collinear.

Answer 6

Ok thanks!
