To determine the image vertices of the polygon KLMN when rotated 270° clockwise, we can apply the general rules for rotation of points in a Cartesian plane.

Rotation Rules:

When rotating a point \((x, y)\) by 270° clockwise, the new coordinates \((x', y')\) are given by: \[ x' = y \] \[ y' = -x \]

Applying to Each Vertex:

  1. Vertex K(0, 0):
    \[ K' = (0, 0) \quad \text{(remains the same)} \]

  2. Vertex L(5, 2):
    \[ L' = (2, -5) \]

  3. Vertex M(5, -5):
    \[ M' = (-5, -5) \]

  4. Vertex N(0, -3):
    \[ N' = (-3, 0) \]

Summary of Rotated Vertices:

  • \(K' = (0, 0)\)
  • \(L' = (2, -5)\)
  • \(M' = (-5, -5)\)
  • \(N' = (-3, 0)\)

However, none of the options you provided match these coordinates correctly.

Let's double-check the specific rotations for each vertex based on the formula:

  1. For vertex L(5, 2):

    • \(L' = (2, -5)\) \(\Rightarrow\) (Matches with the analysis above)
  2. For vertex M(5, -5):

    • \(M' = (-5, -5)\) \(\Rightarrow\) (Matches with the analysis above)
  3. For vertex N(0, -3):

    • \(N' = (-3, 0)\) \(\Rightarrow\) (Matches with the analysis above)

Thus, our calculations confirm the integrity and correctness. In conclusion, based on our transformations, the image vertices of polygon KLMN after a 270° clockwise rotation should be \(K'(0, 0), L'(2, -5), M'(-5, -5), N'(-3, 0)\).

None of the options given in your question reflect this correct transformation output. If you have specifically mentioned any conditions or specific formats for rotation, those should be revisited to find a plausible match in the options provided.
