Question

Given Triangle ABC with A(2, 3), B(0, 6), and C(2,6). Write down the coordinates of the image after the following composition; reflection over the line y = -x followed by a rotation of 90 degrees clockwise.

Answer 1

A"( - 3, 2), B"( - 6, 0), and C"( - 6, 2)

Explanation:

Rotation of 90° clockwise rule :

(x, y) ----> ( y , - x )

A(2, 3), B(0, 6), and C(2, 6)

A'(- 2, - 3), B'(0, - 6), and C'( - 2, - 6)

A"( - 3, 2), B"( - 6, 0), and C"( - 6, 2)
