Thanks!

Answer 1

whats the question

Answer 2

It's from my textbook, I don't really get it.

Answer 3

you need the picture with the other angles too

Answer 4

it says using the protractor on efg you find its 90 in the box, but an obtuse angle in the diagram

Answer 5

it wants you to do the same thing with the other angles

Answer 6

like is aef acute obtuse or right in the box? how about in the diagram?

Answer 7

Ohhhhhh.... lemme take a pic of the other one too

Answer 8

Perhaps you were drunk and measured the angle wrong? ;P

Answer 9

There's the other diagram.

Answer 10

youre going to have to measure it yourself :P i cant really use a protractor on my computer screen

Answer 11

I don't have a protractor tho v.v

Answer 12

@iambatman can you help?? ^.^

Answer 13

@e.mccormick @Compassionate

Answer 14

Well, first off.... if it is a box, what are all the angles?

Answer 15

Erm.. 90 degrees??

Answer 16

Yep. So all the corners are 90 deg in "real life." So the "In the box" part is 90 for everything.

Answer 17

Now the picture is an isometric diagram. This means they used different directions on a picture to represent 3d in 2d.

Answer 18

So, you have a protractor to measure it with?

Answer 19

Nope D:

Answer 20

Hmmm... you might be able to ptint one or use one electronically.

Answer 21

hrm.. is it really needed though?? :o

Answer 22

No, not for just acute obtuse or right. You can eyeball that.

Answer 23

My teacher doesn't actually teach anything, he just tells us what our assignment is & tells us to get it done.
He doesn't actually grade any of these by if we get them right, he grades depending on if we did the problem.. but our tests are actually graded by if we got the problem right or not, which is why I wanna learn how to do the stuff.

Answer 24

Obtuse means > 90
Acute means < 90

Answer 25

^ I knew that

Answer 26

Tbh, they all look acute to me. XD

Answer 27

Well, what about ABC?

Answer 28

Yeah, that looks reeeeeally obtuse. XD

Answer 29

Kk. Now, let me show you something.

ABF, 90, right?

Answer 30

Yeah, I think so

Answer 31

OK, what happens if you extend AB past B to some point X. What is XBF?

Answer 32

Obtuse?? I dunno XD

Answer 33

Nope. It is a simple concept, but you may need to visualize.

Answer 34

Understand what they means and why it works?

Answer 35

Ohhhhhhhh.. that'd be a straight angle.. but what does it have to do with the chart?? XD

Answer 36

Well, it means that FBX, with X out that line, is also 90 deg. So if that is 90, then is FBC more or less than 90?

Answer 37

It is less?

Answer 38

It does not really matter what X is there. It is something more than 0. So 90 + anything is?

Answer 39

Oh, obtuse!!

Answer 40

Hehe. So, that help with how to visualize these?

Answer 41

Yes, though I'm still a bit confused. XD

Answer 42

Well, that one they asked about is obtuse, so not all acute. Now, what part is still confusing?

Answer 43

All the ones on the face are gonna be 90.

Answer 44

All these others are NOT 90 on paper because of how an isomorphic drawing works.
