Question

What is the difference between rotation about the origin and rotation about the center of the figure?

Answer 1

rotation about the origin is the point (0,0) and rotation about the center is any point(x,y)

Answer 2

for the origin x=0 & y-=0

Answer 3

for the center x can equal any value also y...example (2,9) x=2 y=9

Answer 4

So this would be about the center?

Answer 6

ok what exactly is the question i find that for the point H with H' and F with F' \[\left[\begin{matrix}1 & 0 \\ 0 & -1\end{matrix}\right]\] ...what i would also like to know if the topic is matrices

Here is the full question:

Carlos performed a transformation on trapezoid EFGH to create E'F'G'H', as shown in the figure below:
[insert picture i posted before]
What transformation did Carlos perform to create E'F'G'H'?

and the answer choices are:
A. Rotation of 90 degrees counterclockwise about the origin
B. Rotation of 90 degrees counterclockwise about the center of the figure
C. Rotation of 90 degrees clockwise about the origin
D. Rotation of 90 degrees clockwise about the center of the figure

Answer 8

@LynFran So I assume that it would be 90 degrees clockwise, correct? But I'm not sure if it is about the origin or about the center.

Answer 9

to go from F to F' , you need go on which direction to get 90 degree?
