Question

Okay I need help! I don't understand any of this! I went over it thousands of times in the book, but I'm still lost... Attached document in the comments. Thanks!

Answer 1

Here it is. Sorry, my computer froze.

Answer 2

What subject is this for?

Answer 3

geometry

Answer 4

Well the general idea of this problem is that you are creating instructions to take a "shape" that starts in one position and moving it to the next.

Answer 5

Try and think of it as if you were telling someone who was blind, the steps necessary to drag your shape from its starting position to its resting position.

Answer 6

Yeah, okay that makes sense. My problem though, is I don't get what all those small numbers mean, and how they apply to it.

Answer 7

The subscripts tell you what direction you are moving.

Answer 8

Oh, okay, I think I get it. Thanks! So the options with 90 degrees is out of the picture, right?

Answer 9

Wait, no they would definitely be part of the picture, because to flip it, you need to rotate it 90 degrees. Umm, right? :)

Answer 10

They give you a degree and a point about which you rotate.

Answer 11

Last question. In this option, (R y-x° r (90°, P)) (AB) = (XY), I don't really get the y-x and how I use this. I'm pretty sure this is the right answer too.

Answer 12

I believe the first set of subscripts is saying that you move R in the 'y' direction '-x'

Answer 13

Then you will rotate 90 degrees about P

Answer 14

The "R" being AB?

Answer 15

That is one part I am unsure of, they talk about the translation of the line segments in the lower quadrants, but all of the transitions are with respect to the triangles in the upper quadrants.

Answer 16

Oh, well that's okay, you've been a great help, anyways! Thanks, I'll try and figure out the rest from here! You deserve a medal, too! :)

Answer 17

Thanks, Good luck.
