Question

Write the coordinates of the vertices after a rotation 90° clockwise around the origin. G is 9,-1, H is 10,-8, F is 9,-9

Answer 1

To rotate a point \((x, y)\) 90° clockwise around the origin, you can use the following transformation:

\[
(x', y') = (y, -x)
\]

Now, let's apply this transformation to each of the points G, H, and F.

1. **Point G (9, -1)**:
\[
G' = (-1, -9)
\]

2. **Point H (10, -8)**:
\[
H' = (-8, -10)
\]

3. **Point F (9, -9)**:
\[
F' = (-9, -9)
\]

So the coordinates of the vertices after a 90° clockwise rotation around the origin are:

- \(G' = (-1, -9)\)
- \(H' = (-8, -10)\)
- \(F' = (-9, -9)\)
