Question

Here are some points. What are the coordinates of G, H, and I after a rotation about the origin 90 degrees clock-wise?

Answer 1

`G' = (3,1)`

`H' = (-4,0)`

`I' = (-2,-3)`

Explanation:

Given

See attachment for points G, H and E

Rotation: 90 degrees clock-wise

Required

Determine the coordinates after rotation

From the attachment:

`G = (-1,3)`

`H = (0,-4)`

`I = (3,-2)`

When a point (x,y) is rotated 90 degrees clockwise, the new point is: (y,-x)

So, we have:

`G = (-1,3)`

`G' = (3,1)`

`H = (0,-4)`

`H' = (-4,0)`

`I = (3,-2)`

`I' = (-2,-3)`
