Question

Carlos performed a transformation on trapezoid EFGH to create E′F′G′H′ as shown in the figure below.


What transformation did Carlos perform to create E′F′G′H′?

rotation of 90 degrees clockwise about the origin

rotation of 90 degrees clockwise about the center of the figure

rotation of 90 degrees counterclockwise about the origin

rotation of 90 degrees counterclockwise about the center of the figure

Answer 1

I think its either A or B. but i dont no the differnce.

Answer 2

if the rotation is about the center of the figure, the image would still be in the third quadrant....

Answer 3

So it owuld be about the origin,?

Answer 4

yes.....
try this... take point H.... and locate H'.... if you draw segments from each of these points to the origin, you'll see that the angle created is 90 degrees....

Answer 5

oh! okay! i get it now. it does create a 90 degree angle! thank you! :D

Answer 6

yw... :)
