Number 6 I need help on...

OpenStudy (haleyelizabeth2017):
Well, if you rotated it 90 degrees counterclockwise, you'd have A (2, -3), B (2,1), C(4,1) and D(4, -3). There is one more step....think you could figure it out? ;)

Well, rotate it 90 degrees counterclockwise on point A...

Rotation around the origin A? :/
Or how does that work? :/
10 years ago
OpenStudy (haleyelizabeth2017):
you'd reflect it across the y-axis after the first step where you rotate it around point A...I'm not sure how to word that
10 years ago
jabez177 (jabez177):
So first rotate it around the origin 90 degrees.
Then reflect it across the y-axis?

origin would be the middle of the square? I don't know ;~; the second step is correct though

Yeah, that's the tiny little dot in the middle of the graph.

jabez177 (jabez177):
What happens if we rotate it 90 degrees clockwise then reflect it across the x-axis?
10 years ago
OpenStudy (haleyelizabeth2017):
That wouldn't work...but rotating it clockwise and shifting up 6 units might work
10 years ago
jabez177 (jabez177):
Rotating around the origin I meant?

90 degrees clockwise around the Origin, right?
And yes, that makes sense. :)

90 degrees from D

jabez177 (jabez177):
Wait...
Rotating it round the origin won't fit... :/

jabez177 (jabez177):
Okay, thanks! :)

jabez177 (jabez177):

Rotate Rectangle A'B'C'D' 90 degrees around point D? :/
