To determine the rotation that makes a bold uppercase letter "H" look the same, we can analyze the shape of the letter.
- A 90° clockwise or counterclockwise rotation will change the appearance of the "H", as it will not resemble the original letter.
- A 180° rotation (either clockwise or counterclockwise) will turn the "H" upside down and will still look like an "H".
- A 270° counterclockwise rotation (or a 90° clockwise rotation, equivalently) will also not resemble the original letter.
Given these observations, the correct answer is:
3) 180° counterclockwise rotation
So, you would perform a 180° counterclockwise rotation, and the letter will look the same as the original.
