Question

Help needed. Yes or no questions.

Answer 1

20. no
21. yes
22. no
23. yes
24. idk
25. idk

Answer 2

20 = yes
21=no
22= not for sure dk what collinear is but u can look it up
23=idk what coplanar is
24= yes

Answer 3

does the double ended arrow over AB (for example)
mean the the line the passes through A and B?
or
the interval form A to B

Answer 4

is there any information that says that line AB and line EF are parallel? they certainly appear parallel, but its not explicit

Answer 5

iff line AB and EF are parallel then
lines ED and CD will be perpendicular

Answer 6

Since the double ended arrow indicates lines (infinitely long)
line CH is the same as CD, which makes 21 a yes

Answer 7

you have 22 and 23 correct

Answer 8

for 24. the line AB is on the plane M and also on plane GAB, so AB must be the line of inersection

Answer 9

you can always form a plane from three (non-collinear) points

Answer 10

for 25. you just need to look at the right angles in the diagram

Answer 11

so 25 is yes?

Answer 12

yep

Answer 13

Okidokie 20 is a definite yes correct?

Answer 14

well only if you can be sure that lines AB and EF are parallel,
im not sure if this can be assumed

Answer 15

The broken lines are the lines that are behind/under some plane,

if the planes were all coloured-in you wouldn't be able to see the broken lines

Answer 16

does that make sense?

Answer 17

I think #20 is no though

Answer 18

well lines ED is the same line as EF

we know AB is perp to CD because of the right angle

Answer 19

Hmm well I guess if you disregard the length that would be yes, just so weird seeing all yes's and only one no :p

Answer 20

a interval has a certain length
a line is infinitely long

this is why i asked about what the double ended arrow ment

Answer 21

Gotcha, well thank you for spending so much time assisting me I really am grateful for it.
