30 points!

consider the figure shown.

which set of points are collinear?
a) a, d, and e
b) b, c, and d
c) b, c, and f
d) f, b, and d

2)
what is another way to name plane m?
a) plane bcd
b) plane bfd
c) plane ace
d) plane acb

1. B

2. B

Step-by-step explanation:

1. Three points are collinear if they lie on the same line. The diagram shows two triples of points that lie on the same line:

Thus, option B is true.

2. Another way to name the plane is to select three points which do not lie on the same line and write them consequently. As you can see from the diagram, points B, F and D lie on the plane M, but do not lie on the same line. Thus, another way to name plane M is BFD.
