Find 3 uppercase letters that look the same when rotated 180 degrees.Then,what letter's 90,180,270 degree rotations has this outline?This is also the inside lines formed by the rotation of what letter?

180 degrees: H, I, O

Since you don't show "this" outline or "the inside lines", I can't help you with the other two.

and N

you can ust repesent a variable to the problem& you just find it easier with a variable

To find three uppercase letters that look the same when rotated 180 degrees, we can consider letters that have symmetrical shapes. Some examples are:

1. letter "I": It is symmetrical both horizontally and vertically, so when rotated 180 degrees, it still looks like an "I."

2. letter "O": It is a perfect circle, which is symmetrical in any rotation. Thus, when rotated 180 degrees, it remains an "O."

3. letter "S": While the shape of "S" might not be immediately apparent, when you visualize it flipped vertically, it becomes apparent that it is symmetrical. Therefore, when rotated 180 degrees, it will still resemble an "S."

Now, let's move on to the second part of the question. The letter's 90, 180, and 270-degree rotations with this outline, which also forms the inside lines, refers to a letter where rotating it reveals another letter within its shape.

The letter that satisfies this condition is "O." If you rotate it 90 degrees, you get the letter "C" inside it. Rotating it 180 degrees, you get the letter "u" inside it. Finally, if you rotate it 270 degrees, you get the letter "n" inside it.
