Answer:
Step-by-step explanation:
4). Rule for the rotation by 90° counterclockwise about the origin is,
(x, y) → (-y, x)
For the given coordinates,
A(1, 3) → A'(-3, 1)
B(5, 6) → B'(-6, 5)
5). Rule used in question (4) is,
(x, y) → (-y, x)
Option (4) will be the correct option.
6). Coordinates of point C(2, 8) by rotation of 90° counterclockwise about the origin will be,
C(2, 8) → C'(-8, 2)
