Question

Okay For Some Reason This Is A Little Confusing To Me . I Will Fan+Medal
The grid shows Figure Q and its image Figure Q' after a transformation.

Answer 1

Which transformation was applied on Figure Q?

clockwise rotation of 180 DEGREES about the origin

counterclockwise rotation of 90 DEGREES about the origin

clockwise rotation of 90 DEGREES about the origin

counterclockwise rotation of 270 DEGREES about the origin

Answer 2

@whpalmer4

Answer 3

So how many quadrants did it move?

Answer 4

8

Answer 5

?

Answer 6

I do not know how you got that, can you please explain?

Answer 7

Lol Wild Guess , Joking , I counted the spaces from the bottom of the figures and it shows -4 and 4 So I assumed it was 8 , I dont really know what quadrants are ...

Answer 8

Now I'm thinking its 5 :/

Answer 9

ohk h/o read this first: http://www.purplemath.com/modules/plane3.htm

Answer 10

Oh O.O

Answer 11

So... did you read that site too?

Answer 12

Yes so it moved to quadrant 2

Answer 13

ok now, what angle do the x and y axis form?

Answer 14

-5,7?

Answer 15

no no, no I mean, the axes are perpendicular to each other, right?

Answer 16

... I'm So Sorry , I'm Not Sure :./

Answer 17

uhm I'm trying to think of a better way to explain uhm

Answer 18

don't be sorry

Answer 19

so here is my suggestion, I personally can't think of a good way to explain this idea from scratch so I'm going to direct you to some khan academy videos first, then we can talk about it, ok?

Answer 20

Ok :)

Answer 21

This section is entirely what you are working on, if you go through the whole thing, I think you will understand

Answer 22

Awesome

Answer 23

Then come back, tag me and we can go over it. ([provided I'm awake lol)

Answer 24

Lol Okay

Answer 25

KEEP IN MIND THE WAY I DREW IT, THIS IS COUNTER-CLOCKWISE

So think about it like this...

As you go across coordinates...you are at the same time rotating the object...imagine holding a wheel in your hand....as you turn it a full 360 degrees (complete circle) you end u back where you started...

So With that triangle I drew...We start there in quadrant 1..as we move into quadrant 2, the triangle is rotated 90 degrees...it is now on its side....

as we move down into quadrant 3... we have now rotated the object 180 degrees...also known as a half circle and BETTER known as upside down....

finally as we move into quadrant 4...we rotate another 90 degrees to make the triangle go on its other side...now pointing towards the right...

And when (if) we rotate 1 more time...another 90 degrees...we reach 360 degrees...a full circle...and we are back where we started...in quadrant 1...with the triangle right side up
