help plz

Answer 1

Look at the planes ABCD and EFGH shown below:

Answer 2

The two planes intersect along which of the following lines?

ND
MN
AM
AD

Answer 3

ND

Answer 4

how? cause i dont understand

Answer 5

I think it would be MN because that is where the middle of the figures are! It is where they all intersect!

Answer 6

take a look at the graph and look at the line ND

Answer 7

yes, but MN is not a line

Answer 8

What is the difference between AM and ND?

Answer 9

@Michele_Laino

Answer 10

as we can see the intersection occurs at points M and N

Answer 11

ya

Answer 12

but thats not a line

Answer 13

I think that we can refer such intersection to one segment, whose endpoints are just points M and N

Answer 14

ya

Answer 15

so, what is the right option?

Answer 16

one sec i have to do one more question wanna help?

Answer 17

ok!

Answer 18

Square EFGH has been reflected across the x‐axis and then reflected across the y‐axis. Which of the following transformations would return the square to its original position?

Reflection across the line y=x
Reflection across the x‐axis
Reflection across the x‐axis and then reflection across the y‐axis
Reflection across the y‐axis

Answer 19

would A and C be the same

Answer 20

you there?

Answer 21

no, I'm sorry, only one option is the correct option

Answer 22

so whats the right answer
