If kc = 31, what is kn? 74 82 62 43

180° rotation rule  (x, y) → (–x, –y)..

Step-by-step explanation:

Given: Triangle XYZ is rotated to create the image triangle X'Y'Z'. On a coordinate plane, 2 triangles are shown.

The first triangle has points X (-2, 2), Y (1, 2), Z (0, 4).

The second triangle has points X prime (2, - 2), Y prime (- 1, - 1), Z prime (0, - 4).

Here the sign of both coordinates has been changed but the magnitude remains same.

So, the rule is which is for 180° rotation.

Hence, the correct answer is 180° rotation rule  (x, y) → (–x, –y).
