Question

Find the truth value in each statement (true or false).

1) E lies in plane R.

2) CD←→ lies in plane F.

3) C, E, and D are coplanar.

4) Plane F contains ED−→−.

5) B and E are collinear.

6) BC←→ contains F and R.

Answer 1

Coplanar means that the points share a plane. Colinear means the points are on the same line.

Line CD appears to lie on plane F.

Points C and D lie on plane F, and point E lies on plane R.

I cannot tell if segment ED even exists...

B and E do not appear to be on the same line.

I hope this helps!

Answer 2

Dont they lie on multiple planes?

Answer 3

Answer 4

Which ones?

Answer 5

All of them

Answer 6

Hmmm...the only points that seem to appear on both planes are B and C.

Answer 7

Look both the planes go throught each other

Answer 8

Yes, but only notice that line BC touch both planes at one time. The others are only touching one plane at one time.

Answer 9

:O

Answer 10

Haha did you just have a light bulb moment?

Answer 11

Pretty much

Answer 13

Ahh! You have numbers 2, 3, and 5 backwards!

Number 2 should be TRUE because line CD DOES lie on plane F. Look very closely!

Number 3 should be FALSE. Remember that coplanar means that all the points share a plane. Although C and D are both on plane F, E is on plane R.

Number 5 should be FALSE. Remember that colinear means that two points share the same line. B and E are not on the same line.

Other than that, I think you're good.

Answer 14

Don't give up! It can be tricky looking at problems like this.
